ou will see a student survey with 6 questions. This is a fictitious survey that I see y each of the 46,000 fictitious students at StatCrunch U. elow the survey you can set the sample size. Set this to 100 and click Genera oreadsheet will appear with the survey results for your random sample of 10 catCrunchU students. ote: Your sample is a random sample; therefore, your results will differ some ther students' results. ustructions for the lab assignment: How many females are in your sample? How many males? What proportio sample is female? What proportion of your sample is male? (StatCrunch st Tables, Frequency) Is there an equal proportion of men and women at StatCrunchU? а) Show that the conditions are met for the use of a normal model for test (np 2 10 and n(1- p) 2 10, where p is from the null hypothesis). b) Use StatCrunch to test the claim that the proportion of females at S equal to the proportion of men. Paste the StatCrunch printout below. (§ steps: Stat, Proportion Stats, One Sample, With Data. To copy click on C c) Write a conclusion to your hypothesis test referring to females at StatCr d) Explain what the P-value means as a probability that refers to random s 100 StatCrunchU students. What are the proportions of females and males at StatCrunchU? a) Show that the conditions are met for the use of a normal model for a co interval (count of successes and failures are greater than 10).
