A golfer claims that his average golf score at the course he plays regularly is less than 5. A random sample of 30 rounds of golf was selected from a total 250 rounds that were played at the golf course (Population size N=250). The sample mean obtained was 5.085. Assume that the standard deviation for the population of scores for this golfer is 0.308 and a significance level α = 5%. What is the observed value of the test statistic z for the hypothesis test ?

Simon plays golf at his local 18-hole golf course. In his last 20 visits, he works out that he has scored above par on 60% of the holes he has played. For each visit, he models the number 3 es where he scores above par, H, using a binomial distribution: H- B(18, 0.6). Give one assumption that Simon has made in modelling H in this way. a) b) Each time...

A manufacturer claims that the calling range (in feet) of its 900-MHz cordless telephone is greater than that of its leading competitor. A sample of 13 phones from the manufacturer had a mean range of 1060 feet with a standard deviation of 37 feet. A sample of 18 similar phones from its competitor had a mean range of 1050 feet with a standard deviation of 39 feet. Do the results support the manufacturer's claim? Let μ1 be the true mean...
