Answer:

b = 3

Step-by-step explanation:

Use the table to find the slope and y-intercept

Find the slope:

m = (6 - 4)/(3 - 1) = 2/2 = 1

Find b using the pair (1, 4):

4 = 1*1 + b
b = 4 - 1
b = 3

The line is:

y = x + 3

The y-intercept is 3

A sample of 64 was taken from a population, with the mean of the sample being 119 and the standard deviation of the sample being

Fofino [41]

We have the sample size, sample mean and the sample standard deviation. Since the population standard deviation is not know, we will use t-distribution to find the confidence interval.

The critical t value for 95% confidence interval and 63 degrees of freedom is 1.998.

The 95% confidence for the population mean will be:

$(119-1.998 *\frac{16}{ \sqrt{64} } ,119+1.998 *\frac{16}{ \sqrt{64} }) \\ \\ 
=(115.004, 122.996) \\ \\=(115,123)$

Thus, the 95% confidence interval for the population mean will be (115,123)

So, option A is the correct answer
