Find the value of the circumference of a circle with the given diameter.

1 answer:

7 0

C= 2πr, and 2r = D (diameter). So, you can also use this equation: C =Dπ
Since we know the diameter, and we know the value of π, we can easily calculate the value of circumference.
C = Dπ
C = 3.21π
This means that the correct answer is B. 3.21 pi

Consider H0: μ = 45 versus H1: μ < 45. A random sample of 25 observations produced a sample mean of 41.8. Using α = .025 and

a_sh-v [17]

Given
$H0: \ \mu=45 \\ \\ H1: \ \mu\ \textless \ 45$
This is a one-tailed test.

$z= \frac{41.8-45}{6/ \sqrt{25} } = \frac{-3.2}{6/5} = \frac{-3.2}{1.2} =-2.6667$

$P(z\ \textless \ -2.6667)=0.00383$

Since the p-value of the sample statistic (0.00383) is less that the significant level (0.025), we reject the null hypothesis.
