Question

Claim: The mean pulse rate (in beats per minute) of adult males is equal to 68.9 bpm. For a random sample of 134 adult males, the mean pulse rate is 70.1 bpm and the standard deviation is 10.9 bpm. Find the value of the test statistic.

Answer 1

The test statistic can be determined by using the formula

`\begin{gathered} t=\frac{\bar{x}-\mu}{\frac{s}{\sqrt[]{n}}} \\ \text{where} \\ \mu\text{ is the mean} \\ \bar{x}\text{ is the mean of the random sample} \\ s\text{ is the standard deviation of the sample} \\ n\text{ is the number of data sets} \end{gathered}`
