Step-by-step explanation:
Consider the provided information.
The weekly sulfur dioxide emissions follow a normal distribution with a mean of 1000 ppm (parts per million) and a standard deviation of 25.
Thus, μ=1000 and σ = 25
The CEO wants to know if the mean level of emissions is different from 1000.
Therefore the null and alternative hypothesis is:
and
The sample size is n = 50 and ppm.
Now calculate the test statistic by using the formula:
Substitute the respective values in the above formula.
Hence, the correct option is b) 1.70
