A plant in the manufacturing sector is concerned about its sulfur dioxide emissions. The weekly sulfur dioxide emissions follow
egoroff_w [7]

Answer:

The correct option is b) 1.70

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:

H_0:\mu =1000 and H_a:\mu \neq1000

The sample size is n = 50 and \bar x=1006 ppm.

Now calculate the test statistic by using the formula: z=\frac{\bar x-\mu}{\frac{\sigma}{\sqrt{n}}}

Substitute the respective values in the above formula.

z=\frac{1006-1000}{\frac{25}{\sqrt{50}}}

z=\frac{6}{\frac{25}{\sqrt{50}}}=1.697\approx 1.70

Hence, the correct option is b) 1.70

Svet_ta [14]

Answer:

3\frac{3}{8}

Step-by-step explanation:

we  have

(10-6\frac{5}{8})

we know that

10=9+\frac{8}{8}=9\frac{8}{8}

substitute

(10-6\frac{5}{8})=9\frac{8}{8}-6\frac{5}{8}

=(9-6)\frac{8-5}{8}

=3\frac{3}{8}
