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

where m is the gradient and X1 and y1 are the points on the line.

slope= gradient

<em>4=X, 1/3= y</em>

y-1/3 = 3/4 (x-4)
