Question 1.When performing a test of hypothesis at the .05 level of significance, if the p-value is determined to be .04you will reject the null hypothesis.

True or False

Question 2.If the p-value for the slope in a linear regression is less than the level of significance, it means that the slope is not zero.

True or False

Question 3.If household income is normally distributed with a mean of $50,000 and a standard deviation of 10,000, the followingequation will give you the probability of randomly selecting a household with a income of more than $40,000.1- normsdist(-1)

True or False

Question 4.When constructing 90% confidence interval for the one-sample mean (with the population standard deviation known)the z value is approximately (plus or minus) 1.645.

True or False

Question 5.Suppose a non-normal population has a standard deviation of ten. If you take a sample of four observations, thestandard error would be 2.5.

True or False

Question 6.If you construct a 95% confidence interval, there is a 95% chance that the interval will contain the sample mean.

True or False

Question 7.Suppose that a normally distributed population has a mean of 12. The probability of randomly selecting a value of 11 orhigher is less than .50.

True or False

Question 8.As you quadruple the sample size (e.g., go from a sample size of 25 to 100) you cut the standard error in half.

True or False

Question 9.Suppose you are testing the following hypotheses at the .05 level of significance.Ho: mu >=100Ha: mu < 100If your p-value is .75, it would be correct to claim that mu is at least 100.

True or False

Question 10.In multiple regression, if you can prove the slope is not equal to zero, then you can claim that there is a relationshipbetween the two variables.

True or False
