Question 10 Which of the following statements are true? There may be more than one correct statement; check all that are true. [_] a) The chi-square distribution is symmetric about 0. |\\_.| bl The standard normal distribution is symmetric about O. l:' c) The t distribution is symmetric about 0. I: d) The Fdistribution is symmetric about 0. Question 11 Researchers wish to carry out a test of the null hypothesis that the mean of a certain population is 920 against the alternative hypothesis that it is greater than 920. In their situation, they (somehow) happen to know the population standard deviation. They feel comfortable assuming normality for this population, and carry out a Z test. They draw a sample of 26 individuals from this population, and find a Z test statistic of 0.59. What is the p-value of the test? (Give your numeric response to at least 3 decimal places. Give only your numeric response, and not any extra characters or symbols.) Your Answer: \\ . Your Answer Question 12 Which of the following statements about hypothesis testing are true? There may be more than one correct statement: check all that are true. l_l a} The p-value is a probability, and as such must lie between 0 and 1. l._,l bl If the null hypothesis is false, we cannot make a Type II error. l:l c) If the null hypothesis is false, the p-value will always be less than 0.05. l_l cl) The greater the p-value, the stronger the evidence against the null hypothesis
