Assume we are given a sample of customer interarrival times in a candy shop: 31 33 12 14 9 33 30 27 15 24 17 13 20 28 27 10 13 16 9 23 20 16 13 16 a) Test if the variance between arrivals is no more than 43 with 5% level of significance. (State a null and alternative hypothesis) b) Find the smallest Type 1 error probability that allows us to reject Ho. (Define an interval for such Type 1 error probability).

9) In a sample of 50 business trips taken by employees in the HR department, a company finds that the average amount spent for the trips was $1450 with a standard deviation of $450. In a sample of 80 trips taken by the employees in the sales department is $1650 with a standard deviation of $700. When testing the hypothesis (at the 5% level of significance) that the variance of the amount spent on trips is significantly larger in one department than the other, what is the null and alternative hypotheses? *please write out the null and alternative hypotheses below AND on scratch work*

The data in the table below are summary statistics of the daily output (in tonnes) of random, independent samples of 6 copper mines in Free State, 8 copper mines in Northern Cape and 6 copper mines in Mpumalanga. Assume that the daily output of copper mines is normally distributed in all three countries. Daily copper mine output Free state Northern Cape Mpumalanga Sample mean 501 739 779 Sample standard deviation 169 195 221 a. Perform a one-way analysis of variance (ANOVA) to determine the following: SSTr, SSE, SST, MSTr, MSE and F statistic. b. At the 5% level, test the hypothesis that the mean daily output levels of copper mines in these three provinces are equal. (In answering this question, clearly state the null and alternative hypotheses, test statistic and critical value). c.
