For each of the examples below, go through the four steps of hypothesis testing; report your results in APA format. Use alpha of .05 and a two tailed test for each example. According to 2014 data from the Centers for Disease Control and Prevention, the average life expectancy in the United States is 78.74 years with other sources listing the standard deviation, σ, for this data as 16.5 years. A researcher is interested in determining if rock musicians die at an earlier age and collects a random sample of 45 dead rock musicians. The researcher finds an average age of death of 45.2 years for the sample. Use this statistic to evaluate the researcher’s hypothesis.
A school district claims that the average salary of elementary school teachers in their district is more than the national average of $42,000. A sample of 30 elementary school teachers from that district have a mean salary $43,260. The standard deviation for the population is $5,230. At α = 0.05, test their claim that teachers in their district earn more than $42,000 per year.

Assume the population standard deviation is $724. If the significance level is 5%, can the null hypothesis be rejected?
Calcium levels in people are normally distributed with a mean of 9.7 mgdL and a standard deviation of 0.5 mgdL .

Step 4:Sketch the normal distribution and find the critical regions. Step 5:Compute the test statistic. Step 6:Make a decision Step 7:Summarize the results.
