Note: For this problem, your answer should be rounded to two decimal places. In a particular municipality, it is believed that 25 percent of homes are not properly insulated. In order to test ?0:?=.25 vs. ??:?≠.25 (where ? is the population proportion of homes that are not properly insulated) a random sample of 300 homes was selected. In the sample, it was found that 108 homes were not properly insulated. If the null hypothesis is true, then the z-score for the sample proportion is:

The output below is for a t-test for the hypothesis: Individuals living in bad neighborhoods commit more crime than those living in good neighborhoods. The data in the Group Statistics section provides you with the average number of crimes committed by individuals living in good and bad neighborhoods and the standard deviation of this same variable. The findings of significance are located in the Independent Samples Test section. Pay particular attention to the "t" column and the "Sig (2-tailed)"column. The "t" column is the t value that you would have calculated by hand (as we learned in class). The "Sig (2-tailed)"column provides you with the p value (the level of significance of this relationship). In this column, any value below .05 indicates that you would have rejected your null hypothesis. 1. Can someone tell me about the relationship of all these data? I'm trying to determine if my hypothesis, listed below, can be proven or disproven? 2. What is the independent variable and…
Solve the problem. The systolic blood pressures of the patients at a hospital are normally distributed with a mean of 138 mmHg and a standard deviation of 12.8 mmHg. Find the two blood pressures having these properties: the mean is midway between them and 90 % of all blood pressures are between them. (Hint: the area between the two values is 0.9. Since they are symmetrical on either side of the mean, that leaves an area of 0.1 divided by 2 = 0.05 in the tails of the distribution.) ο οο 126.5 mm Hg, 149.5 mm Hg 116.9 mm Hg, 159.1 mm Hg 117.9 mm Hg, 160.1 mm Hg O.121.6 mm Hg, 154.4 mm Hg
You are performing a left-tailed test with test statistic z=−2.04, find the p-value to 4 decimal places.Note: You will need to use the z and t sheet to get this answer.
You wish to test the following claim (H.) at a significance level of a = 0.001. For the context of this problem, Ha = 42 - 4i where the first data set represents a pre-test and the second data set represents a post-test. H.: Hd = 0 Ha:Ha + 0 You believe the population of difference scores is normally distributed, but you do not know the standard deviation. You obtain pre-test and post-test samples for n = 40 subjects. The average difference (post - pre) is d = 2.8 with a standard deviation of the differences of sa = 19.9.
