Answer:
10353
Step-by-step explanation:
The given series is in arithmetic progression since the common difference is same which is 8.
To find the sum of series we can simply apply the formula'
S= n/2( first term + last term)
S is the sum and n is the number of terms
we also need to find the number of terms n
n = (last term- first term)/2 + 1
n= 51
s= 10353

Answer:
The 98 percent confidence interval for the population mean is between 27.85 and 29.75 subjects.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the mean subtracted by M. So it is 28.8 - 0.9488 = 27.85 subjects.
The upper end of the interval is the mean added to M. So it is 28.8 + 0.9488 = 29.75 subjects.
The 98 percent confidence interval for the population mean is between 27.85 and 29.75 subjects.
