An experiment was conducted to determine whether the price of a golf club affected the distance a golfer could hit a golf ball. A sample of 60 golfers were randomly assigned to one of two groups, c or e. The 30 golfers in group c were given a club and told the price of the club was cheap; the 30 golfers in group e were given the same club and told the price of the club was expensive. In reality, there was no difference in price. The golfers used their assigned clubs to hit a golf ball as far as they could. The distance, in yards, that each golfer hit the golf ball was recorded, and the mean distance calculated for each group. A two-sample t-test for a difference in means will be conducted

Answers

Answer 1

The true statements about the data from the t-test will be:

The data was collected using random assignment, the golfers were assigned randomly to the two groups.The data was also collected using random selection.The distribution of the difference in the sample means will be normally distributed as well according to the central limit theorem.

What is a t-test?

The table below lists the means and standard deviations for 5th graders in the district and for the norm group for student performance in four different subjects. According to the table, the performance of the 5th graders in the district is more variable than that of the norm group in which subject(s)?

Answers

Using the coefficient of variation, it is found that the performance of the 5th graders in the district is more variable than that of the norm group in Geography and Science.

What is the coefficient of variation of a distribution?

It is given by the division of the standard deviation by it's mean.

Researching this problem on the internet, we have that for geography, the class mean and SD are given, respectively, by 75 and 12, while the norm is of 10 and 85, hence:

[tex]CV_c = \frac{12}{75} = 0.16[/tex]

[tex]CV_n = \frac{10}{85} = 0.12[/tex]

In English, the mean and SD are 100 and 10, respectively, for both, hence:

[tex]CV_c = \frac{10}{100} = 0.11[/tex]

[tex]CV_n = \frac{10}{100} = 0.11[/tex]

In Spelling, they are for the class of 125 and 12, for the norm 15 and 120, hence:

[tex]CV_c = \frac{12}{125} = 0.096[/tex]

[tex]CV_n = \frac{15}{120} = 0.125[/tex]

In Science, they are for the class of 90 and 20, for the norm 15 and 90, hence:

[tex]CV_c = \frac{20}{90} = 0.2222[/tex]

[tex]CV_n = \frac{15}{90} = 0.1667[/tex]

Hence the class is more variable in Geography and Science.

A person weighing 0. 70 kn rides in an elevator that has an upward acceleration of 1. 5 m/s2. What is the magnitude of the force of the elevator floor on the person?

Answers

The magnitude of the force of the elevator floor on the person is; 807.13 N

What is the Magnitude of force?

We are given;

Weight; W = 0.7 KN

Acceleration; a = 1.5 m/s²

There are only two forces acting on the person: which are his weight W (downward) and the normal force N of the floor against the body (upward). Thus the equilibrium equation here is;

N - W = F

N - W = ma

Here, m is the mass of body, and its value is calculated as;

W = mg

0.7 = 9.81m

m = 0.7/9.81

m = 71.42 kg

Thus;

N - 0.7 = 71.42 * 1.5

N = 0.7 + (71.42 * 1.5)

N = 807.13 N

Answers

If  john drops a stone and the stone hits the water 3 m in front of the boat. The speed of the boat is: 12m/sec.

Speed

First step is to find the time

-19.6 m = -1/2 ×9.8 m/s² × t²

0 = -4.9t²  + 19.6

-19.6  = -4.9t²

t²=  19.6 / 4.9  

t  =√(19.6 / 4.9)

t=√4

t = 2 seconds

Second step is to calculate the speed using this formula

Speed=Distance/Time

Let plug in the formula

Speed=27 - 3/2

Speed=  24/2

Spee= 12m/sec
