Question

Last year, 46% of business owners gave a holiday gift to their employees. A survey of business owners indicated that 40% plan to provide a holiday gift to their employees. Suppose the survey results are based on a sample of 60 business owners.

(a) How many business owners in the survey plan to provide a holiday gift to their employees?

(b) Suppose the business owners in the sample do as they plan. Compute the p value for a hypothesis test that can be used to determine if the proportion of business owners providing holiday gifts has decreased from last year. If required, round your answer to four decimal places. If your answer is zero, enter “0”. Do not round your intermediate calculations.

(c) Using a 0.05 level of significance, would you conclude that the proportion of business owners providing gifts has decreased? We ______the null hypothesis. We _________conclude that the proportion of business owners providing gifts has decreased from 2008 to 2009. What is the smallest level of significance for which you could draw such a conclusion? If required, round your answer to four decimal places. If your answer is zero, enter “0”. Do not round your intermediate calculations. The smallest level of significance for which we could draw this conclusion is______ ; because p-value______ α=0.05, we_______ the null hypothesis.

A recent survey stated that 37% of pet owners talk to their pets
on the telephone. A veterinarian believes that the proportion
should be lower than the survey's claim. In a random sample of 180
pet owners, 33.9% of them said they spoke to their pets on the
telephone. Find the following while performing a hypothesis test to
see if there is sufficient evidence that the proportion of pet
owners that talk to their pets on the telephone is lower...

The Congressional Budget Office reports that 36% of federal
civilian employees have a bachelor's degree or higher (The Wall
Street Journal). A random sample of 123 employees in the
private sector showed that 32have a bachelor's degree or higher.
Does this indicate that the percentage of employees holding
bachelor's degrees or higher in the private sector is less than in
the federal civilian sector? Use α = 0.05.
