Gnesinka [82]

We are given the following data:

Sample Size = n = 1000

Sample Mean = u = 15 hours

Population Standard Deviation = s = 2 hours

Since we know the population standard deviation, we can use z distribution to find the confidence interval about the mean. z value for 95% confidence interval is 1.96.

Formula for the confidence interval is:

(u-z\frac{s}{\sqrt{n}} ,  u+z\frac{s}{\sqrt{n}})

Using the values in the formula, we get:

(15-1.96\cdot\frac{2}{\sqrt{1000}},  15+1.96\cdot\frac{2}{\sqrt{1000}})\\ \\  (14.88,15.12)

Therefore, the 95% confidence interval about the population mean is 14.88 hours to 15.12 hours. So B option is the correct answer.

Why doesn’t inverse variation have no x and y intercept?
kirill115 [55]

Answer:

Since k is constant, we can find k given any point by multiplying the x-coordinate by the y-coordinate. For example, if y varies inversely as x, and x = 5 when y = 2, then the constant of variation is k = xy = 5(2) = 10. Thus, the equation describing this inverse variation is xy = 10 or y = .

I hope this was the answer u were looking for.
