a. How many business owners in the survey planned to provide a holiday gift to their employees this year? Round your answer to the nearest whole number. b. Suppose the business owners in the sample do as they plan. Conduct a hypothesis test that can be used to determine whether the proportion of business owners providing holiday gifts had decreased from last year. State the hypotheses. 0.47
H_(a):p
0.47 Compute the test statistic and
p
-value.
z
-value (to 2 decimals)
p
-value (to 4 decimals) c. Using a 0.05 level of significance, would you conclude that the proportion of business owners providing gifts decreased?
H_(0)
. We | conclude that the proportion of business owners providing gifts has decreased from last year to this year. What is the smallest level of significance for which you could draw such a conclusion? (to 4 decimals) Last year, 47% of business owners gave a holiday gift to their employees. A survey of business owners conducted this year indicates that 40% planned to provide a holiday gift to their employees. Suppose the survey results are based on a sample of 90 business owners.
