David wants to test a claim about a population mean. The population standard deviation is unknown, the sample is a simple random

sample of size 20, and the population is normally distributed. In this case, the t-test should be used since σ is unknown. If David incorrectly uses the z-distribution instead of the t-distribution, will he obtain a P-value that is too big or too small? Explain your thinking. Will he be more likely or less likely to reject the null hypothesis than if had correctly used the t-distribution?

Answer:

a)The P-value will be too small

b) He will reject the Null hypothesis

Step-by-step explanation:

a) If David incorrectly uses the z-distribution instead of the t-distribution, he will obtain a p-value that is too small   because p-values obtained using Z distribution are smaller when compared to p-values obtained using t-distribution

b) He will reject the Null hypothesis given that the P value he will obtain will be very different from the one he obtained using z-distribution

The length of a rectangle is three times it's width. The perimeter of the rectangle is 100 inches. What are the dimensions of th
Pavel [41]

Answer:

Dimensions : 37.5 * 12.5

length : 37.5

width : 12.5

Step-by-step explanation:

let x = length and y = width

x = 3y based on info from problem

Perimeter = 2(length + width)

100 = 2(x + y)

substitute 3y for x

100 = 2(3y + y)

100 = 2(4y)

100 = 8y

y = 12.5

x = 3(12.5) = 37.5
