- Matt thinks that he has a special relationship with the number 1. In particular, Matt thinks that hewould roll a 1 with a fair 6-sided die more often than you'd expect by chance alone. Suppose p is the trueproportion of the time Matt will roll a 1.(a) State the null and alternative hypotheses for testing Matt's claim. (Type the symbol "p" for thepopulation proportion, whichever symbols you need of "<", ">", "=", "not =" and express any values as afraction e.g. p = 1/3)HH.(b) Now suppose Matt makes n = 46 rolls, and a 1 comes up 10 times out of the 46 rolls. Determine the P-value of the test:P-value =(c) Answer the question: Does this sample provide evidence at the 5 percent level that Matt rolls a 1 moreoften than you'd expect?(Type: Yes or No)15) The school newspaper surveyed 100 commuter students and asked two questions.
