**Answer 1**

**Answer:**

reject the null hypothesis or fail to reject the null hypothesis.

**Answer 2**

The two decisions that perform the **hypothesis test **includes **fail **to **deny** the **null hypothesis**, and **deny **the **null hypothesis. **

**Hypothesis testing** refers to the testing that can give access to the reliability of the hypothesis via sample data.

There are two types of decisions that are considered to be wrong while performing the **hypothesis test** is:

In the case when the hypothesis is true but i.e. rejected. This is known as a type I error.In the case when the hypothesis is false, but it is failed to reject it. This is known as a type II error.

So, the decisions that should not be considered while performing the **hypothesis test** is:

Acceptance of the alternative hypothesis.Acceptance of the null hypothesis.Fail to deny the alternative hypothesis.Deny the alternative hypothesis.Making of type I error.Making of type II error.

Therefore we can conclude that options D and option E are considered from performing a **hypothesis test.**

The science teacher gives daily homework. For a random sample of days throughout the year, the median number of problems is 5 and the IQR is 2. The Spanish teacher also gives daily homework. For a random sample of days throughout the year, the median number of problems is 10 and the IQR is 1. If you estimate the median number of science homework problems to be 5 and the median number of Spanish problems to be 10, which is more likely to be accurate? Explain your reasoning.

### Answers

Answer:

SCIENCE SEEMS MORE ACCURATE

Step-by-step explanation:

The interquartile range (IQR) = difference between the upper and lower quartile (Q3 - Q1)

The median can be estimated as :

(Q3 - IQR/2) or (Q1 + IQR/2).

FOR SCIENCE:

MEDIAN NUMBER = 5

IQR = 2

IQR = Q3 - Q1

Q3 = median + IQR/ 2 = 5 + 2/2 = 6

Q1 = median - IQR/2 = 5 - 2/2 = 4

FOR SPANISH:

MEDIAN = 10

IQR = 1

IQR = Q3 - Q1

Q3 = median + IQR/ 2 = 10 + 1/2 = 10.5

Q1 = median - IQR/2 = 10 - 1/2 = 9.5

Science has a lower median score and an interquartile range which is reasonable wider than Spanish with a larger median value (but a very narrow interquartile range).

The probability of a tourist visiting an area cave is 0.70 and of a tourist visiting a nearby park is 0.60. The probability of both places on the same day is 0.40. The probability that a tourist visits at least one of these two places is

### Answers

The **probability** that the tourist visits **atleast one** of the two places is **0.90**

Probability of cave visit, **P(C) = 0.70**

Probability of park visit = **P(N) = 0.6 **

Probability of both = **P(B) = 0.40**

The **probability** of visiting **atleast one** of the two places can be defined thus :

**P(Atleast one) = P(C) + P(N) - P(B) **

P(Atleast one) = 0.70 + 0.60 - 0.40

P(Atleast one) = **0.90**

Therefore, the **probability** of visiting **atleast one** of the two places is **0.90**

Suppose that a tea company estimates that its monthly cost is C(c) = 500x² + 100x and its monthly revenue is R(2) = -0.6x3 + 700x2 – 400x + 300, where x is in thousands of boxes of tea sold. The profit is the difference between the revenue and the cost. What is the profit function, p(X)?

O A. P(x) = 0.6x3- 200x2 + 500x+ - 300

OB. P(x) = -0.6x3 + 1200x2 – 300x + 300

O C. P(x) = -0.6x3 + 200x2 – 500x + 300

D. P(xl = 0.6x3 + 200x2 – 500x + 300

### Answers

**Answer:**

**p(x) = 0.6x³ - 200x² + 500x- 300**

**Step-by-step explanation:**

Given the cost function and revenue function as:

C(x) = 500x² + 100x

R(x) = -0.6x³ + 700x² – 400x + 300

**To get the profit function:**

p(x) = C(x) - R(x)

p(x) = 500x² + 100x -(-0.6x³ + 700x² – 400x + 300)

**open the parenthesis**

p(x) = 500x² + 100x + 0.6x³ - 700x² + 400x - 300

p(x) = + 0.6x³+500x² - 700x² + 100x+ 400x- 300

**p(x) = 0.6x³ - 200x² + 500x- 300**

**Hence the profit function is expressed as p(x) = 0.6x³ - 200x² + 500x- 300**

D - division

A - Addition

S - Subtraction

Now solve the parentheses first;

Round your final answer to each part to three decimal places, but do not round during intermediate steps. The relative risk of being a college graduate for Boone County residents as compared to Cooper County residents is

### Answers

**Answer:**

The relative risk of being a college graduate for Boone County residents as compared to Cooper County residents is **3.11**.

**Step-by-step explanation:**

Denote the events as follows:

*C* = Cooper County resident

*B* = Boone County resident

*G* = graduate

*NG* = non-graduate

The information provided is summarized as follows:

G NG Total

C 18 82 100

B 28 22 50

Total 46 104 150

Compute the relative risk of being a college graduate for Boone County residents as compared to Cooper County residents as follows:

[tex]\text{Relative Risk}=\frac{\text{Graduates in Boone County}}{\text{Graduates in Cooper County}}[/tex]

[tex]=\frac{28/50}{18/100}\\\\=\frac{28}{50}\times \frac{100}{18}\\\\=3.11111\\\\\approx 3.11[/tex]

Thus, the relative risk of being a college graduate for Boone County residents as compared to Cooper County residents is **3.11**.

The **relative risk** of remaining a college graduate for **Boon County residents **in comparison to Cooper County residents would be **0.500**

Relative risk:

**Relative risk** is used in the statistical analysis of the data of **ecological, cohort,** medical, and **intervention studies**, to estimate the strength of the association between exposures **(treatments or risk factors)** and outcomes. Mathematically, it is the incidence rate of the outcome in the **exposed group.**

The relative risk is calculated by dividing the **probability** of an event for **group 1 **divided by the probability** **of an event occurring for **group 2.**

Simon score 4x10^2 points in a game. Joe scored 2x10^3 points in the same game. whose score is higher? how much higher?

### Answers

**Answer:**

Joe scored higher by 1600

**Step-by-step explanation:**

**Given**

[tex]Simon = 4 * 10^2[/tex]

[tex]Joe = 2 * 10^3[/tex]

**Solving (a): Which is higher?**

**First, we need to convert both numbers to whole numbers**

[tex]Simon = 4 * 100[/tex]

[tex]Simon = 400[/tex]

[tex]Joe = 2 * 10^3[/tex]

[tex]Joe = 2 * 1000[/tex]

[tex]Joe = 2000[/tex]

**2000 is greater than 400;**

**Hence, Joe score higher**

**Solving (b): By how much?**

**Answer:**

**Step-by-step explanation:**

The expression 10=1,000 is obviously false, but we can make it true by rewriting it with an exponent.

Note that 1,000=10*10*10

Or, equivalently:

[tex]1,000=10^3[/tex]

Thus, if we modify the original false expression and add an exponent 3 to the base 10, then it would be true:
