Question
An agency reported that in a recent year 35.6% of businesses that employed 200 persons or more received orders via the Internet Assume a more recent survey has been carried out in 3,799 businesses that employ 200 or more persons Res
1,475 of them have received orders via the Internet during the past 12 months. Complete parts (a) and (b) below.
Click here to view page 1 of the cumulative standardised normal distribution table.
Click here to view page 2 of ihe cumulative standardised normal distmbulion table
The level of significance is 0.05 and the sample size is 3,799. Use the Z-test statistic, and use the normal distribution for a sampling distribution.
Determine the critical value(s) that divide(s) the rejection and non-rejection region(s).
The critical value(s) is(are)
(Round to two decimal places as needed. Use a comma to separate answers as needed)
Calculate the value of the test statistic
Z= (Round to two decimal places as needed)
Make the statistical decision and state the managerial conclusion. Choose the correct answer below.
O A. Reject Ho There is insufficient evidence that the mean percentage is less than 35 6%.
O B. Do not reject H. There is insufficient evidence that the mean percentage is less than 35 6%.
O C. Do not reject Ho There is sufficient evidence that the mean percentage is less than 35.6%
O D. Reject Ho There is sufficient evidence that the mean percentage is less than 35.6%
b. Use
five-step p-value approach Interpret the meaning of the p-value
Use the same 0 05 level of significance. The first three steps are identical to those above. For the next step, find the p-value
p-value
(Round to three decimal places as needed)
