SAT Reading Scores An instructor claims that the variance of SAT critical reading scores for females is different than the variance of SAT critical reading scores for males. The table shows the SAT critical reading scores for 9 randomly selected female students and 13 randomly selected male students. At 1% level of signicance, can you support the instructor's Claim? SAT Female 480 610 340 630 520 690 540 600 800 560 680 360 530 380 460 630 310 730 740 520 560 400 Instructions I Step 1: Specify the hypotheses: 0 H0: Variance of Population 1 is equal to Variance of Population 2. O H A3 Variance of Population 1 is not equal to Variance of Population 2. I Step 2: Test statistic and related Pvalue. O StatCrunch will compute an Fvalue test statistic and the related Pvalue. 0 Copy and paste the Hypothesis test results table below. I Step 3: Make a decision based on comparing the Pvalue with the level of significance, alpha, as follows: 0 If PValue less than or equal to alpha, reject HO. 0 If PValue greater than alpha, fail to reject H0. I Step 4: State your conclusionStep by Step Solution
