v A psych _ I studied the alcohol consumption patterns of people in two age groups. One group consisted of people aged 21 to 35, and the other oonsisted of people aged 36 to 50. The psychologist interviewed random and independent samples from each group. She assigned a score from 0 to 100 to each individual (a soore of 0 meant no alcohol consumption) according to factors such as the frequency and the amount of alcohol consumed. The results from the study are summarized below. {The rst row gives the mole sizes, the second row gives the gmm, and the third row gives the sgmwm.) Assume that the scores of all people aged 21 to 35 are approximately normally distributed. Assume the same for the scores of all people aged 36 to 50. Can we conclude, at the 0.01 signicance levelIr that the variance of the scores of all people aged 21 to 35, of, is greater than the variance of the scores of all people aged 36 to 50, 6:? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your answers as specied below. {If necessary, consult a \"it of formulas.) v (a) State the null hypothesis H0 and the alternative hypothesis H1. H0 : I] H1:|:| (b) Determine the type of test statistic to use. (Choose one) 7 (c) Find the value of the test statistic. (Round to three or more decimal places.) [I (d) Find the critical value at the 0.01 level of signicance. (Round to three or more decimal places.) I] (e) Can we conclude that the variance of the scores of all people aged 21 to 35 is greater than the variance of the scores of all people aged 36 to 50? OYes O No
