Give as much information as you can about the P-value of a t test in each of the following situations. (Use technology to calculate the P-value. Round your answers to four decimal places.) USE SALT (a) two-tailed test, df = 7, t = 0.79 (b) upper-tailed test, df = 10, t = -0.70 (c) lower-tailed test, n = 20, t = -2.20 (d) lower-tailed test, n = 20, t = -5.30 (e) two-tailed test, n = 40, t = 1.50
Need the H0 and H1 values. Can use != for not equal to.

Part I [15 poins]: 1. Suppose you were to explain to a person who has not yet studied statistics that a statistical test has just resulted in the rejection of the null hypothesis that a population mean u is equal to 0. That is, H:H = 0. has been rejected, say, at the 5 percent level of significance. Which of the following is a more accurate statement? (a) The evidence of the data indicated that the population mean differs significantly from 0. (b) The evidence of the data was significant enough to indicate that the population mean differs from 0.
Help me answer the following question in the pictures with the information below: Women athletes at a certain university have a long-term graduation rate of 67%. Over the past several years, a random sample of 36 women athletes at the school showed that 21 eventually graduated. Does this indicate that the population proportion of women athletes who graduate from the university is now less than 67%? Use a 10% level of significance.
You are conducting a test of independence for the claim that two different populations have the same proportions of the following two characteristics. Here is the sample data. Category A B A Population Population #1 #2 B 9 57 The expected observations for this table would be Population Population Category 21 119 What is the chi-square test-statistic for this data? 2 x² Report all answers accurate to three decimal places.
Consider the following data on price ($) and the overall score for six stereo headphones tested by a certain magazine. The overall score is based on sound quality and effectiveness of ambient noise reduction. Scores range from 0 (lowest) to 100 (highest). Brand Price ($) Score A 180 76 В 150 69 C 95 63 70 54 E 70 38 F 35 24 (a) The estimated regression equation for this data is ŷ 21.258 + 0.327x, where x = price ($) and y = overall score. Does the t test indicate a significant relationship between price and the overall score? Use a = 0.05. State the null and alternative hypotheses. Ho: B1 + 0 Ha: B1 Ho: B1 Ha: B1 + 0 = 0 O Ho: Po = 0 Ha: Bo + 0 O Ho: B1 2 0 Ha: B1 < 0 O Ho: Po + 0 Hai B = 0 Find the value of the test statistic. (Round your answer to three decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value

answer 1
true or false. when finding the p-value of a chi-square test, we always shade the tail areas in both tails.
