As described in z-distribution the answers are given below:

a) The 95% confidence interval estimate for the population mean spending by a customer on visiting salon per month is given as follows: (747, 853).

b) The sampling error at 95% confidence level is of: $35.78.

What is a z-distribution ?

The normal distribution with a mean of 0 and a standard deviation of 1 is referred to as the standard normal distribution (also known as the Z distribution) (the green curves in the plots to the right). It is frequently referred to as the bell curve since the probability density graph resembles a bell.

solution:

The bounds of the confidence interval are given as follows:

In which:

is the sample mean.

z is the critical value.

n is the sample size. is the standard deviation for the population.

The parameters for this problem are given as follows:

Hence the lower bound of the interval is of:

800 - 200 x 1.96/square root of 55  = 747.

The upper bound of the interval is of:

800 + 200 x 1.96/square root of 55  = 853.

The sampling error for a sample size of 120 is calculated as follows:

200 x 1.96/square root of 120 = $35.78.

Can someone tell me the slope ?
borishaifa [10]

Answer:

slope = 4

Step-by-step explanation:

We can find the slope of a line when knowing 2 points by using the slope formula, \frac{y_2 - y_1}{x_2 - x_1}. x_1 and y_1 represent the x and y values of the first point, respectively. x_2 and y_2 represent the x and y values of the second point, respectively.

The two points we have are (2,8) and (0,0). So, in this case, x_1 = 2, y_1 = 8, x_2 = 0, and y_2 = 0. Let's substitute those values into the formula and solve to get the slope:

m  = \frac{0-8}{0-2}

\frac{-8}{-2}

4

So, the slope is 4.
