A technology committee wants to perform a test to see if the mean amount of time students are spending in a lab has increased from 55 minutes. Here are the data from a random sample of 12 students. a) Plot the data. Are any of the observations outliers? Explain. b) What do you conclude about the claim? If there are outliers, perform the test with and without the outliers present. 0 Time (min.) m 160 0- 0 Time (min.) 160 The test statistic is t = (Round to two decimal places as needed.) ... TTT 0 Time (min.) 160 0- 0 Are there any outliers? Select the correct choice below and fill in any answer boxes within your choice. A. There are 2 outliers, because those points are significantly different from the rest of the data. B. There are no outliers. All of the points are grouped together in the histogram. b) Write appropriate hypotheses for the test. Ho: μ = 55 HA: H>55 Time (min.) 52 75 58 54 55 135 76 74 63 9 51 61 Time (min.) 160 O
