Answer: 0.9927
Step-by-step explanation:
We assume that the number of earthquakes that occur in Los Angeles follows normal distribution.
As per given , we have
Sample size : n= 35
Let 
be the sample mean.
Now ,
Hence, the probability that the mean of the sample is between 34 and 37.5. is 0.9927 .

Answer:
Solution given:
x. 
f. fx
13. 15. 195
14. 42 588
15. x. 15x
16. 10. 160
17. 3. 51
. n=70+x. 
=994+15x
we have
mean=sum/n
14.44=
14.44=
doing crisscrossed multiplication
(70+x)*14.44=994+15x
1010.8+14.44x=994+15x
15x-14.44x=1010.8-994
0.56x=16.8
x=16.8/0.56
x=30
