The length of fish were measured at 3 different lakes. Lake 1: 3.5, 4.2, 6.1, 5.2 Lake 2: 3.1, 3.2, 4.3, 2.1 Lake 3: 5.6, 7.1, 4.4, 4.1, 6.2 Is there evidence to suggest that the average length is not the same at all 3 locations? Group of answer choices There is not evidence to suggest the average length of fish is different at one of the lakes. There is evidence to suggest that the average length is different at one of the lakes. Enter the test statistic (to 4 decimal places)
The average house has 14 paintings on its walls. Is the mean larger for houses owned by teachers? The data show the results of a survey of 14 teachers who were asked how many paintings they have in their houses. Assume that the distribution of the population is normal. 15, 13, 16, 16, 17, 14, 14, 15, 13, 13, 15, 16, 15, 16 What can be concluded at the a = 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Но: ? Select an answer v H: ?v Select an answer v c. The test statistic ? v = (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? va f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest that the population mean number of paintings that are in teachers' houses is not significantly more than 14 at a = 0.01, so there is insufficient evidence to conclude that…
What is one indication that there are paired samples in a data set? Choose the correct answer below. O A. Knowing the value that a subject has in one group gives one no information about the value in the second group. OB. Each observation in one group is coupled with one particular observation in the other group. OC. The researcher is comparing two populations. O D. The researcher is working with two distinct groups in the data set.
