A university administrator obtains a sample of the academic records of past and present scholarship athletes at the university. The administrator reports that no significant difference was found in the mean GPA (grade point average) for male and female scholarship athletes ( P = 0.287 ) . This means that: a. the maximum difference in GPAs between male and female scholarship athletes is 0.287.
b. the chance of obtaining a difference in GPAs between male and female scholarship athletes as large as that observed in the sample if there is no difference in mean GPAs is 0.287.
c. the GPAs for male and female scholarship athletes are identical, except for 28.7% of the athletes.
d. the chance that a pair of randomly chosen male and female scholarship athletes would have a significant difference in GPAs is 0.287.

Answer:

A university administrator obtains a sample of the academic records of past and present scholarship athletes at the university. The administrator reports that no significant difference was found in the mean GPA (grade point average) for male and female scholarship athletes ( P = 0.287 ). This means that - the GPAs for male and female scholarship athletes are identical, except for 28.7% of the athletes. (Option C)

Step-by-step explanation:

The probability of obtaining results as extreme as the observed results of a statistical hypothesis test, assuming that the null hypothesis is correct is known as p-value.

The p-value is used as an option to reject points to provide the smallest level of significance at which the null hypothesis would be rejected. A smaller p-value means that there is stronger evidence in favor of the alternative hypothesis.

Only the statement expressed by option C is in correlation with the meaning of p-value.

The sum of x and -15 is 23

Answers

Answer: x=38

Step-by-step explanation:

x+(-15)=23

x-15=23

+15  +15

x=38

When there is a positive and negative sign the negative sign cancels the positive sign.

Answer:

38

Step-by-step explanation:

23+15=38 because in order to get 23 from -15 a negative number you need to have 38 to silence the -15.

11 The net force on a vehicle that is accelerating at a rate of 1.5 m/s² is 2,800 newtons. What isthe mass of the vehicle to the nearest kilogram?

Answers

Answer:

Mass = 1867kg

Step-by-step explanation:

Given

Force = 2800N

Acceleration = 1.5m/s^2

Required

Determine the mass of the vehicle

This question will be answered using Newton's second law

Force = Mass * Acceleration

Substitute values for Force and Acceleration

2800 = Mass * 1.5m/s^2

Make Mass the subject

Mass = (2800N)/(1.5m/s^2)

Mass = 1866.6667kg

Mass = 1867kg ---- approximated

Hence, the mass of the vehicle is 1867kg
