A group of local businessmen is thinking about developing land into a shopping mall. To evaluate the desirability of the location, they count the number of shoppers who visit the neighboring shopping center each day. A random sample of 53 days reveals a daily average of 116 shoppers with a standard deviation of 45 shoppers. The businessmen will develop the land if the average number of shoppers per day is more than 100. Based on the sample data, should the businessmen develop the land? Perform a hypothesis test and use a significance level of a = 0.02. Assume the population of the number of daily shoppers is approximately normally distributed. Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below. Answer Ho: μ = 100 Ha M O < O # 100 Keypad Keyboard Shortcu Tables

• Question 16 A news article that you read stated that 53% of voters prefer the Democratic candidate. You think that the actual percent is different. 122 of the 272 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.10 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ?v| Select an answerv (please enter a decimal) H1: |?vSeect an answerV (Please enter a decimal) c. The test statistic ?v = (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ?v a f. Based on this, we should Select an answerv the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the population proportion is not significantly different 53% at a = 0.10, so there is not sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is different 53%. O The data…
