Question

Homework4: Problem 7 Previous Problem Problern List Next Problem (6 points) Matt thinks that he has a special relationship with the number 4. In particular, Matt thinks that he would roll a 4 with a fair 6-sided die more often than you'd expect by chance alone. Suppose p is the true proportion of the time Matt will roll a 4. la) State the null and alternative hypotheses for testing Matt's claim. (Type the symbol "p" for the population proportion, whichever symbols you need of "<", ">", "=', 'not =" and express any values as a fraction e.g.p=1/3) Ho = H = (b) Now suppose Matt makes n = 50 rolls, and a 4 comes up 11 times out of the 50 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 4 more often than you'd expect? (Type: Yes or No)

Answer 1
