Question

Assume that females have pulse rates that are normally distributed with a mean of 74 bpm and a standard deviation of 12.5 bpm16 adult females are randomly selected find the probability that they have pulse rates with a mean less than 80 bpm

Answer 1

Answer:

The probability is 0.68439

Step-by-step explanation:

The Probability is obtained as follows:

`\begin{gathered} p(x<80)=p(z<(x-u)/(\sigma)) \\ \\ =p(z<(80-74)/(12.5)) \\ \\ =p(z<(6)/(12.5)) \\ \\ =p(z<0.48) \\ \\ =0.68439 \end{gathered}`
