Rashid [163]

Answer: 3.5308

Step-by-step explanation:

Claim : The firm's professionals volunteer an average of more than 15 hours per month.

i.e. $\mu>15$

Null hypothesis : $H_0:\mu\leq15$

Alternative hypothesis : $H_1:\mu>15$

Sample size : $n=24$

The sample mean : $\overline{x}=16.6\text{ hours}$

Sample standard deviation : $\sigma=2.22\text{ hours}$

The test-statistics for the population mean is given by :-

$z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

i.e. $z=\dfrac{16.6-15}{\dfrac{2.22}{\sqrt{24}}}=3.5307960256\approx3.5308$

Hence, the correct value of the test statistic for the appropriate hypothesis test is 3.5308.
