### Hypothesis Testing Example**Claim:** The mean pulse rate (in beats per minute) of adult males is equal to 69 bpm. For a random sample of 160 adult males, the mean pulse rate is 69.4 bpm and the standard deviation is 10.8 bpm. **Task:** Find the value of the test statistic.**Answer Box:** - [ ]*(Round to two decimal places as needed.)*### ExplanationTo test this claim, we will use the formula for the test statistic for a sample mean:\[ z = \frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}}} \]Where: - \(\bar{x}\) is the sample mean (69.4 bpm) - \(\mu\) is the population mean as stated in the claim (69 bpm) - \(\sigma\) is the standard deviation of the sample (10.8 bpm) - \(n\) is the sample size (160) Use this formula to calculate the test statistic to assess the validity of the claim.
