You think that the a and tind that 84% returned, www.csun.edu/counts/one_year_continuation_rate-plip a. What is p? _ What is the number of successes? What is n? b. Write the hypotheses: Circle the best definition of p. the proportion of all of last year's freshmen who returned the proportion of all 2014 CSUN freshmen who returned the proportion of all CSUN freshmen among the 250 who returned C. Assuming that Ho is true, the sampling distribution of p has a mean of Use the formula to compute the SE of the sampling distribution of p. Complete this sketch of the sampling distribution of p. Put a scale on the horizontal axis. Then locate the result from the sample and shade in area representing the p-value. (Is the area representing the p-value on one side or two sides?)

- AttachedThere are 3 parts to this question!! Answer each part in a separate blank! The average price per square foot for a home in a large county in a certain state is $225. The council of a country town wonders if the mean price of the homes in their town is less than the mean price of the homes in the county. The town council selected a random sample of 9 homes that have recently sold in their town. They found the price per square foot and want to perform a hypothesis test at the 0. 05 significance level. The data is listed below. 221.4 213.1 219.1 229.6 220.7 224.4 221.6 217.8 223.9 1. Calculate the test statistic and the P-value. 2. What is the decision at the given significance level? 3. What do you conclude?In a sample of 1000 people in maharashra, 540 are rice eaters and the rest are wheat eaters. Can we assume that both rice and wheat are equally popular in this State at 1% level of significance?
