Question 6 < > Testing: H : A = 45.1 < 45.1 Your sample consists of 38 subjects, with a mean of 43.1 and standard deviation of 4.7. Calculate the test statistic, rounded to 2 decimal places. t Question 7 You wish to test the following claim (Ha) at a significance level of a = 0.10. Ho:p=71.7 < 71.7 You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n = 87 with mean M = 70.4 and a standard deviation of SD = 13.6. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value= The p-value is... O less than (or equal to) a greater than a This test statistic leads to a decision to... O reject the null accept the null fail to reject the null Question 8 You are performing a two-tailed test with test statistic z = -0.01, find the p-value to 4 decimal places Question 9 Based on the data shown below, calculate the correlation coefficient (rounded to three decimal places) x y 5 42.75 6 40.64 7 37.33 8 34.52 9 34.11 10 33.8 11 29.89 12 13 15 16 234567 29.48 25.97 14 26.66 23.45 21.54 17 23.03 18 19.32 19 19.21 20 15.8 C
