1) For a one tailed hypothesis test, you determine the critical value to be Z_crit= 1.960 and the test score to be Z_test

= 0.64. Should you REJECT or NOT reject the null hypothesis?

Reject H0

Do NOT reject H0

Not enough information to determine

2) You surveyed 81 households and asked them how much they spent on transportation each month. This SAMPLE produced a mean of $851 with a standard deviation of $274. If you want to construct a Confidence Interval for household transportation costs each month,

(a)What is the POINT ESTIMATE for household transportation costs each month? $Answer to the nearest dollar

(b)At the 98% confidence level, what is the MARGIN OF ERROR (E) for household transportation costs each month?$Answer to 2 decimal places

3) For a two tailed hypothesis test, you determine the critical value to be Z_crit= 1.960 and the test score to be Z_test = 2.73.

a) What is the p-value for this hypothesis test?

b) Based on this p-value, should you reject or not reject the null hypothesis at the 0.05% significance level?

A. Reject H0

B. Do not Reject H0

C. No enough information to determine
