Answer:
As 
, it is possible to reject null hypotesis. It means that the local mean height is less tha 0.7 m with a 5% level of significance.
Step-by-step explanation:
1. Relevant data:
2. Hypotesis testing
3. Find the rejection area
From the one tail standard normal chart, whe have Z-value for 
is 1.56
Then rejection area is left 1.56 in normal curve.
4. Find the test statistic:
5. Hypotesis Testing
As , it is possible to reject null hypotesis. It means that the local mean height is less tha 0.7 m with a 5% level of significance.
The blank is 123 because 32/41=96/123.
your multiplying 32 by 3 to get 96.
That means you have to multiply the bottom by 3 too.
41 multiplied by 3 is 123.
And 123 is the blank.
The absolute value of B is 1 3/5 because although B is in the negatives, absolute value makes it positive.
