A drug company is testing a new drag which is supported to reduce blood pressure. From the nine people who are used as subjects,

Pie

Answer:

The 95% confidence interval for the mean change in blood pressure, $\bar{x}$ , is 1.744 < $\bar{x}$ < 2.816

Step-by-step explanation:

The parameters given are;

The number of people in the sample, n = 9

The average drop in blood pressure, $\bar{x}$ = 2.28 points

The standard deviation, σ = 0.82

The confidence level = 95%

The formula for confidence interval with a known mean is given as follows;

$CI=\bar{x}\pm z_{\alpha/2} \dfrac{\sigma}{\sqrt{n}}$

Where:

$z_{\alpha/2}$ = z - score at 95% confidence level = 1.96

We therefore have;

$CI=2.28 \pm 1.96 \times \dfrac{0.82}{\sqrt{9}}$

Which gives the 95% confidence interval for the mean change in pressure, $\bar{x}$ , is given as follows;

1.744 < $\bar{x}$ < 2.816

How does erics drawing show that 13 is a prime nunber?

Alina [70]

1 to 100 of Prime Numbers
2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97.
The number 15 has divisors of 1,3,5,15 because:
15/1=15
15/3=5
15/5=3
15/15=1
So 15 is not a prime number.
The number 13 has only two divisors of 1,13.
13/1=13
13/13=1
So 13 is a prime number.
