Awedding caterer randomly selected clients from the past few years and recorded the months in which the wedding receptions were held. she was interested in testing a claim that weddings occur in different months with the same frequency. she found the test statistic to be χ2 = 10.600. use a 0.05 significance level to find the critical value for the goodness-of-fit and test the claim that weddings occur in different months with the same frequency. then state the conclusion.

According to a research study, parents with young children slept 6.4 hours each night last year, on average. a random sample of 18 parents with young children was surveyed and the mean amount of time per night each parent slept was 6.8. this data has a sample standard deviation of 0.9. (assume that the scores are normally distributed.) researchers conduct a one-mean hypothesis at the 5% significance level, to test if the mean amount of time parents with young children sleep per night is greater than the mean amount of time last year. the null and alternative hypotheses are h0: μ=6.4 and ha: μ> 6.4, which is a right-tailed test. the test statistic is determined to be t0=1.89 using the partial t-table below, determine the critical value(s). if there is only one critical value, leave the second answer box blank.

Astudy of 80 english composition professors showed that they spent, on average, 14.6 minutes correcting a student's term paper. construct and interpret a 90% confidence interval of the mean time for all composition papers. assume that the population standard deviation is 2.9 minutes. round to 1 decimal.
