A group of local businessmen is thinking about developing land into a shopping mall. To evaluate thedesirability of the location, they count the number of shoppers who visit the neighboring shoppingcenter each day. A random sample of 54 days reveals a daily average of 116 shoppers with a standarddeviation of 46 shoppers. The businessmen will develop the land if the average number of shoppersper day is more than 110. Based on the sample data, should the businessmen develop the land?Perform a hypothesis test and use a significance level of a = 0.05. Assume the population of thenumber 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.Ho :μ = 110Ha:μ110

According to a report on consumer fraud and identity theft, 20% of all complaints for a year were for identity theft. In that year, Oregon had 714 complaints of identity theft out of 3449 consumer complaints. Does this data provide enough evidence to show that Oregon had a higher proportion of identity theft than 20%? Test at the 5% level. State the hypotheses. Họ: P ?v Ha: P ? Calculate the test statistic. Round to four decimal places. Calculate the standardized test statistic. Round to three decimal places. z = Find the p-value. Round to four decimal places. p-value = State your decision. O Since the p-value is less than .05, reject Ho. O Since the p-value is greater than .05, fail to reject Ho. O Since the p-value is greater than .05, reject Ho- O Since the p-value is less than .05, fail to reject Ho- Interpret the results. O At the 5% level of significance, there is not enough evidence to show that the proportion of complaints due to identity theft in Oregon is less than 20%. O At…
Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.

This is the step1, so step 2 and step 3 must be answered. (Step 2: Test Statistic -Pearson's r correlation coefficient AND Step 3: Critical Values ) so based it from the photo. Show COMPLETE SOLUTIONS. The table shows the number of hours spend by 30 students in studing and their test scores. Solve for the Pearson’s r and interpret the results. Use 5% significance level. Step 1: Null and Alternative Hypothesis Ho: r = 0; There is no significant relationship between the number of hours spent studying and the students test scores. Ha: r ≠ 0; There is a significant relationship between the number of hours spent studying and the students test scores.
