3.A genetic experiment involving peas yielded one sample of offspring consisting of421green peas and148yellow peas. Use a0.01significance level to test the claim that under the samecircumstances,27%of offspring peas will be yellow. Identify the nullhypothesis, alternativehypothesis, teststatistic, P-value, conclusion about the nullhypothesis, and final conclusion that addresses the original claim. Use theP-value method and the normal distribution as an approximation to the binomial distribution.

What is the teststatistic?

4.Systolic blood pressure levels above120mm Hg are considered to be high. For the100systolic blood pressure levels listed in the accompanying dataset, the mean is121.82000mm Hg and the standard deviation is15.43993mm Hg. Assume that a simple random sample has been selected. Use a0.01significance level to test the claim that the sample is from a population with a mean greater than120mm Hg.

Identify the test statistic.(Round to two decimal places asneeded.)

Identify theP-value.(Round to three decimal places asneeded.)

5. Listed below are the lead concentrations in g/g measured in different traditional medicines. Use a 0.10 significance level to test the claim that the mean lead concentration for all such medicines is less than 16 g/g. Assume that the sample is a simple random sample.
