Also shown are the SPSS results from analysis of variance. Assume that we plan to use a 0.05 significance level to test the claim that the different car sizes have the same mean amount of chest compression.

Wait times were reported by Disney and wait times at 10 AM and 5 PM were recorded on 50 different days (five rows are shown in the accompanying table). Use the 10 AM wait times for Space Mountain, Rock 'n' Roller Coaster, Tower of Terror, and Flight of Passage. Use a 0.05 significance level to test the claim that the four rides have the same mean wait time at 10 AM. Click the icon to view the data table of wait times. Determine the null hypothesis. Ho: H1 = H2 = H3 = H4 Determine the alternative hypothesis. H1: At least one of the means is different from the others Determine the test statistic.

Errors were recorded in a test of visual and motor skills for a treatment group of 24 people who drank ethanol and another group of 24 people given a placebo. The errors for the treatment group have a standard deviation of 2.20, and the errors for the placebo group have a standard deviation of 0.84. Assume that the two populations are normally distributed. Use a 0.05 significance level to test the claim that both groups have the same amount of variation among the errors. Let sample 1 be the sample with the larger sample variance, and let sample 2 be the sample with the smaller sample variance. What are the null and alternative hypotheses? O A. Ho : 01 = 07 OB.
