X=2, y=4. Easiest way to solve this problem is to have the y's cancel out. Multiply the first equation by -2 and the bottom by 3. You'd want to do one as a negative number since both are already negative; making one positive makes everything easier.
Here you should find x = 2.
Then plug it back into one of the equations to solve for y.
y = 4. Check you work by plugging it back in.

The age of the residents in a certain town is Normally distributed with an unknown mean μ and unknown standard deviation σ . The
Helen [10]

Answer:

0.149

Step-by-step explanation:

Here the hypothesized mean=35

Null hypothesis:μ=35

Alternative hypothesis:μ>35

It is clearly stated in the problem that the mayor thinks average age is now lower that is hypothesized mean is greater.

we know that n=40,xbar=36 and s=6.

we don't know about population standard deviation and the estimate sample standard deviation is given so, we use t-test statistic.

t=(xbar-μ)/(sd/sqrt(n))=36-35/6/(sqrt(40)) = 1.0541

The p-value is calculated using t-test statistic and the alternative hypothesis. Using excel function T.DIST.RT(1.0541,39) we get p-value=0.149

RT(right tailed) is used because alternative hypothesis is μ>35.

Hence the p-value is 0.149.
