X+x+2+x+2+2x-5=49
you would then combine all the x’s
which would equal 5x+2+2-5=49
the you would add up your numbers =ing
5x+-1=49
then add -1 to the other side of the = sign making the one positive which would equal
5x=50
divide by 5
x=10

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

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.
