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

The proportion of people who live after fighting cancer is 0.75. Suppose there is a new therapy that is used to increase the survival rate. Use the parameter p to represent the population portion of people who survive after fighting cancer. For a hypothesis test of the therapy’s effectiveness, researchers use a null hypothesis of p = 0.75. Pick the correct alternative hypothesis. 1. p > 0.75 2. p < 0.75 3. p 6= 0.75
