Each year, all final year students take a mathematics exam. It is hypothesized that the population mean score for this test is 8
drek231 [11]

Answer:

95% Confidence interval:  (96.06,103.94)

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 85

Sample mean, \bar{x} = 100

Sample size, n = 30

Alpha, α = 0.05

Population standard deviation, σ = 11

95% Confidence interval:

\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

100 \pm 1.96(\frac{11}{\sqrt{30}} ) = 100 \pm 3.94= (96.06,103.94)

(96.06,103.94) is the 95% confidence interval for  the population mean test score.

What is the value of this expression 6 • [(32 - 8) divided by 4 + 2]
zalisa [80]

Answer:

48 is your answer.

Step-by-step explanation:

What you want to do is follow PEMDAS.

Parenthesis are first. You will subtract 32 and 8 to get 24.

6 x [(24)/4+2] You will then divide 24 and 4 to get 6.

6 x[6+2] you will then add 6+2 to get 8.

6 x 8 = 48 is your answer.
