Tollowing statements are true matched pairs)? cerning the mean of the ences between two dependent samples Select all that apply. A. If one has more than 15 matched pairs of sample data, one can consider the sample to be large and there is no need to check for normality. B. The methods used to evaluate the mean of the differences between two dependent variables apply if one has 89 IQ scores of men from Ohio and 89 IQ scores of men from Texas. C. If one has ten matched pairs of sample data, there is a loose requirement that the ten differences appear to be from a normally distributed population. D. If one wants to use a confidence interval to test the claim that μ> 0 with a 0.05 significance level, the confidence interval should have a confidence level of 90%. E. The requirement of a simple random sample is satisfied if we have independent pairs of convenience sampling data.

The average house has 11 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. 12, 13, 12, 12, 12, 11, 13, 12, 13, 11, 10, 12, 11, 13 What can be concluded at the a = 0.05 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 H1: Select an answer c. The test statistic ? ▼ (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 (? v f. Based on this, we should | Select an answer the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the population mean is not significantly more than 11 at a = 0.05, so there is sufficient evidence to conclude that the population mean number of paintings that are in teachers' houses…

Subject : Basic Statistics 11. I've posted an image of the question.

Listed in the accompanying table are heights (in.) of mothers and their first daughters. The data pairs are from a journal kept by Francis Galton. Use the listed paired sample data, and assume that the samples are simple random samples and that the differences have a distribution that is approximately normal. Use a 0.01 significance level to test the claim that there is no difference in heights between mothers and their first daughters. Mother 61.0 69.0 60.0 66.0 65.5 64.0 63.5 63.0 68.5 69.0 D Daughter 63.5 68.0 62.0 67.0 65.2 69.0 63.5 63.0 66.0 70.0 In this example, Ha is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the daughter's height minus the mother's height. What are the null and alternative hypotheses for the hypothesis test? Ho: Hd in. H1: Hd in. (Type integers or decimals. Do not round.) Identify the test statistic. t= (Round to two decimal places as needed.) Identify the P-value. P-value =…

MEASURES OF CENTRAL TENDENCY AND VARIABILITY.1. Suppose two classes achieved the following grades on a math test,Class A: 64, 70, 73, 77, 85, 90, 94Class B: 74, 75, 75, 76, 79, 80, 94 In each class, find the mean, median, mode, range, interquartile range, Variance,Standard Deviation, coefficient of variance Which class is better?
