The cost of a college education has increased at a much faster rate than costs in general over the past twenty years. In order to compensate for this, many students work part- or full-time in addition to attending classes. At one university, it is believed that the average hours students work per week exceeds 20. To test this at a significance level of 0.05, a random sample of n = 20 students was selected and the following values were observed:26 15 10 40 10 20 30 36 40 0 5 10 20 32 16 12 40 36 10 0Based on these sample data, which of the following statements is true?a. The standard error of the sampling distribution is approximately 3.04.b. The test statistic is approximately t = 0.13.c. The research hypothesis that the mean hours worked exceeds 20 is not supported by these sample data. d. All of the above are true
