1. The numbers below represent the body temperature of six subjects taken at 8am and again at 3pm. Use significance level of .05 to test the claim that theres a difference in temperatures due to time of day.

8am 97.8, 97, 98.5, 97.4, 97.4, 99

12am 98, 98.6, 99.1, 98.2, 97.8, 98.8

Please provide Ho,Ha,Right and left tail, two tails, critical value, alpha, test-statistic, p-value, decision and conclusion

In a study of the accuracy of fast food orders one restaurant had 38 orders that were not accurate among 349 orders observed. Use a significance level of .05 test the claim that the rate of inaccurate orders is equal to 10%.

The excel data are for the mean body and brain temperature of six ostriches was recorded at typical hot conditions. The results, in degrees Celsius. Ostriches live in hot environments, and they are normally exposed to the sun for long periods. Mammals in similar environments have special mechanism for reducing the temperature. Test for a mean difference in temperature between body and brain for these ostriches. Paste the statistics output from excel Find the test statistic, p-value Interpret the results...
