Radiation in Baby Teeth Listed below are amounts of strontium-90 (in millibecquerels, or mBq, per gram of calcium) in a simple random sample of baby teeth obtained from Pennsylvania residents and New York residents born after 1979 (based on data from “An Unexpected Rise in Strontium-90 in U.S. Deciduous Teeth in the 1990s,” by Mangano et al., Science of the Total Environment). Use a 0.05 significance level to test the claim that the median amount of strontium-90 from Pennsylvania residents is the same as the median from New York residents.

Step 1

The claim that the median amount of strontium-90 from Pennsylvania residents is the same as the median from New York residents is null hypothesis. Thus, the alternative hypothesis is the median amount of strontium-90 from Pennsylvania residents is not same as the median from New York residents.

The hypotheses are given below:

Step 2

**Software procedure:**

Step-by-step procedure to obtain *P*-value using the MINITAB software is as follows:

- Choose
**Stat > Nonparametrics > Mann-Whitney.** - In
**First Sample**, enter the column of**Pennsylvania**. - In
**Second Sample**, enter the column of**New York**. - Enter value of the
**Confidence level**as**95**. - Select
**not equal**as the**Alternative**. - Click
**OK**.

Output using the MINITAB software is given below:

Step 3

From the output, the *P*-value is 0.0111.
