For employees at a large company, the mean number of overtime hours worked each week is 9.2 hours with a population standard dev
topjm [15]

Answer:

z=\frac{9.3-9.2}{\frac{1.6}{\sqrt{49}}}= 0.4375

And we can use the normal table and the complement rule we got:

P(z>0.4375)= 1-P(z

Step-by-step explanation:

For this case we have the following parameters given:

\mu = 9.2 , \sigma =1.6

We select a ample size of n=49. And we want to find this probability:

P(\bar X> 9.3)

And for this case is a right tail probability and we can use the z score formula given by:

z=\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}

And replacing we got:

z=\frac{9.3-9.2}{\frac{1.6}{\sqrt{49}}}= 0.4375

And we can use the normal table and the complement rule we got:

P(z>0.4375)= 1-P(z
