Can you help with this please?

insens350 [35]

Answer:

Step-by-step explanation:

the answer is A. if you notice the y-intercept, it its at -5

A is the only answer choice that gives -5 as the y-intercept

another way to make sure that A is the right answer is to calculate the slope

when you increase 3 units UP (y), you increase 5 units to the RIGHT (x)

since slope is y/x, it should be 3/5 which is also in A

another way to check A is to plug in points

hope this helps!

Brian Vanecek, VP of Operations at Portland Trust Bank, is evaluating the service level provided to walk-in customers. According

77julia77 [94]

Answer: (14.18, 15.08)

Step-by-step explanation:

Given : Sample size : n= 64

Sample mean : $\overline{x}=15$

Standard deviation : $\sigma=4$

Significance level : $\alpha: 1-0.90=0.1$

Critical value : $z_{\alpha/2}=1.645$

The confidence interval for population mean is given by :-

$\overline{x}\pm\ z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=15\pm(1.645)\dfrac{4}{\sqrt{64}}\\\\\approx15\pm0.82\\\\=(14.18,\ 15.08)$

Hence, the 90% confidence interval for the population mean of waiting times is (14.18, 15.08).
