You wish to test the claim that the average IQ score is less than 100 at the .10 significance level. You determine the hypotheses are: Ho: μ=100Ho: μ=100 H1:μ<100H1:μ<100 You take a simple random sample of 73 individuals and find the mean IQ score is 95.2, with a standard deviation of 15.1. Let's consider testing this hypothesis two ways: once with assuming the population standard deviation is not known and once with assuming that it is known. Round to three decimal places where appropriate.

A television show conducted an experiment to study what happens when buttered toast is dropped on the floor. When 51 buttered slices of toast were dropped, 33 of them landed with the buttered side up and 18 landed with the buttered side down. Use a 0.01 significance level to test the claim that toast will land with the buttered side down 50% of the time. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution. After that, supposing the intent of the experiment was to assess the claim that toast will land with the buttered side down more than 50% of the time, write a conclusion that addresses the intent of the experiment.
In a one-tail hypothesis test where you reject H0 only in the lower tail, it was found that the p-value is 0.1469 if ZSTAT=−1.05.

Reject the null hypothesis because the p-value is less than the level of significance. B. Reject the null hypothesis because the p-value is greater than the level of significance. C. Fail to reject the null hypothesis because the p-value is greater than the level of significance. D. Fail to reject the null hypothesis because the p-value is less than the level of significance.
