Answer:
The 4th one to the Right
Step-by-step explanation:
Whats the topic that you want me to tell about
Assuming yo mean $8.798
ok, so look at the cents ones
9
look at previous term
8
8 is bigger than 5 so round up
9 rounded up is 10
so
8.80 is rounded
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.
