3 fours + 3 fours = ..... fours
4+4+4 + 4+4+4 = 24
24÷4 = 6
so 3 fours + 3 fours = 6 fours
(2.26×108)/0.013=244.08/0.013=18775.4

Answer:
ohhhh we have the same question
Step-by-step explanation:
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.
