Calculation:
The procedures to test the representative claim are given below:
Step 1: Identify the claim and state the null and alternative hypotheses.
Step 2: Identify the level of significance and find the critical values and rejection regions.
Step 3: Obtain the test statistic value.
Step 4: Make decisions about deciding whether to reject or fail to reject the null hypothesis
Step 5: Interpret the decision in the context of the original claim.
Nonparametric tests:
When the distribution of the population is not known or when the population distribution does not follow the normality, then the non-parametric statistical tests are used to test the population parameters.
Parametric tests:
When the distribution of the population is known or when the population distribution follows the normality, then the parametric statistical tests are used to test the population parameters.
The nonparametric tests are used for testing the median, the relation between the variables,and the randomness along with Spearman rank correlation coefficient and the parametric tests are used for testing mean, proportion, and variance.
Here, the claim is that “the median tenure for workers from the representative's district is less than the national median tenure of 4.6 years”,
Thus, the nonparametric tests are used for testing the given claim.

A company is marketing a new product they say works better than the traditional test tube. There is so much interest in the product that 30 different labs around the world are testing the claim that this product is actually better. If each study uses an alpha level (alpha) of .10, and if the null hypothesis is true (that the test tube isn't any better that the traditional one), how many of the hypothesis tests would we expect to incorrectly find statistical significance (that is, conclude that the new test tube is better, when it actually isn't)?

Hypothesis Testing Review
For each problem below, simply identify the null and alternative hypotheses. Use appropriate notation/symbols. You do not have to run any hypothesis tests, although it's good practice and I'll post answers for all of them.
1) A simple random sample of 44 men from a normally distributed population results in a standard deviation of 10.7 beats per minute. The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with a 0.10 significance level to test the claim that pulse rates of men have a standard deviation equal to 10 beats per minute.
2) In 1997, a survey of 880 households showed that 145 of them use e-mail. Use those sample results to test the claim that more than 15% of households use e-mail. Use a 0.05 significance level.

You have been given the task of designing a study concerning the lifetimes of five different types of electric motor. The initial question to be addressed is whether there are differences in mean lifetime among the five types. There are 20 motors, four of each type, available for testing. A maximum of five motors can be tested each day. The ambient temperature differs from day to day, and this can affect motor lifetime. a. Describe how you would choose the five motors to test each day. Would you use a completely randomized design? Would you use any randomization at all? b. If Xij
represents the measured lifetime of a motor of type i tested on day j, express the test statistic for testing the null hypothesis of equal lifetimes in terms of the Xij.

If a report states that certain data were used to reject a given hypothesis, would it be a good idea to know what type of test (one-tailed or two-tailed) was used? Explain.
asked 2020-12-24
For the same data, null hypothesis, and level of significance, if the conclusion is to reject \(H_{0}\) based on a two-tailed test, do you also reject Ho based on a one-tailed test? Explain.
