Reject or Fail to reject h0 The table below includes results from polygraph (lie detector) experiments conducted by researchers. In each case, it was known if the subjected lied or didnot lie, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent ofthe polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truth and lies?Click the icon to view the table......Determine the null and alternative hypotheses.O A.

USE 3 DECIMAL A producer claims that his potato chips weight has a normal distribution at least 150 grams. The manager tries to test day shift production weight is heavier that night shift. Because of the complaints of the customers, quality control department select randomly 19 bags from the day shift and find the mean as 146 grams and variance 9 grams and randomly selected 21 bags from the night shift and find the mean as 148 grams and variance 8 grams. If manager want to test the claim as night shift mean weight of the product is greater than that of day shift at 1% level of significance. Calculate the test statistics. (H1: m night shift > m day shift).
Q1 Identify the statement below that best describes why we chose the mean as our preliminary model. a) The mean is a balancing point about which the sum of the residuals is zero. b) The mean is the value that minimizes the sum of squares and therefore minimizes the variance. c) The mean is the value that minimizes the sum of sqaures and therefore minimizes the standard deviation. d) All of the above.
