You wish to test the claim that the average IQ score is less than 100 at the .005 significance level. You determine the hypotheses are: Ho:u= 100 H1:4 < 100 You take a simple random sample of 72 individuals and find the mean IQ score is 96.7, with a standard deviation of 15.5. Let's consider testing this hypothesis two...

2) A random sample of black bears were weighed at various times of the year. Some of the bears were weighed in the spring, some in the summer and some in the fall. The bears were tagged so that the same bear was not measured more than once. Use a 1% significance level and the following Statcato statistics, graphs and ANOVA printout to test the population claim that the time of year (season) is related to the weight of the...
