Answers

Question attached

Answer and explanation:

Here we would use the two sample t test. In finding the hypotheses for a two sample t test we test the sample mean of one group against the other group to determine if there is a statistical difference or they are equal. We have this to compare the mean finger tapping rate of the two groups being tested in the question. Our null and alternative hypotheses here are:

H0: u1 = u2 null hypothesis

H1: u1 > u2 alternative hypothesis

Where u1 and u2 are the sample means for each group in the caffeine experiment

The distance between two towns is 120 kilometers there are approximately 8 kilometers in 5 miles which measurement is closest to the number of mules between these two towns

Answers

Answer:

75 Kilometers

Step-by-step explanation:

We have been given that the distance between two towns is 120 km.

We are also told that there are approximately 8 km in 5 miles. Let us find number of miles per km by dividing 5 by 8.

\text{Number of miles in 1 km}=\frac{5\text{ miles}}{\text{8 Km}}

\text{Number of miles in 1 km}=0.625\frac{\text{ miles}}{\text{ Km}}

Therefore, there are 0.625 miles in 1 km.

To convert our given distance into miles we will multiply our given distance by number of miles in 1 km.

\text{Number of miles in 120 km}=120\text{ km}\times \frac{0.625\text{ miles}}{\text{ km}}

\text{Number of miles in 120 km}=120\times 0.625\text{ miles}

\text{Number of miles in 120 km}=75\text{ miles}

Therefore, the distance between two towns is 75 miles.

Brayden is 2 yards tall. His sister is 61 inches tall. How much taller is Brayden than his sister​

Answers

Answer:

11 inches

Step-by-step explanation:

2 yards = 72 in

72 in - 61 = 11 in

Brayden is 11 inches taller than his sister. There are 36 inches in a yard because there are 3 feet in a yard. Each foot has 12 inches. 12 times 3 is 36. Brayden is two yard tall so multiply 36 by 2 and you will find that Brayden is 72 inches tall. Now, you would subtract 61 from 72 and you would get 11. Brayden is 11 inches taller than his sister
