Question
Mean = 5.40 and standard deviation = 2.30 Calculate standard error for each of the sample sizes a) Standard error for n= 100 b) Standard
Mean = 5.40 and standard deviation = 2.30
- Calculate standard error for each of the sample sizes
a) Standard error for n= 100
b) Standard error for n=250
c) Standard error for n= 500
d) Standard error for n=1000
2. Find confidence interval using formula for 95% confidence Interval
a) CI for n=100 (use 1.96 value and you will get 2 values- below and above the given mean
b) CI for n=250
c) CI for n=500
d) CI for n=1000
3. Find confidence interval using formula for 99% confidence interval
a) CI for n=100 (use 2.58 value and you will get 2 values- below and above the given mean
b) CI for n=250
c) CI for n=500
d) CI for n=1000
