Answer:
The 95% confidence interval for the mean score is:
∈ 
Step-by-step explanation:
We want to estimate the population mean, that is, the average score of all the subjects.
An estimator for the population mean μ is 
Since the sample size is 
then we use the statistic 
with 
degrees of freedom
The confidence interval for the mean is:
Where
is the average score of the sample
is the standard deviation of the sample
is the sample size
for a confidence level of 95% and 26 degrees of freedom
Then confidence interval is
∈
The only thing I can see that you can do with this is to move the 2 up to make it an exponent on the 5: log(base 7) = 5^2. Is that what you mean?
10in would be the appropriate scale factor for the drawing. 2000 is 10x200. If each inch represents 200 feet, then you would need 10 to reach the desired scale factor of the original building
Answer:
15 days
Step-by-step explanation:
Total hours required =
16×5×6 = 480
Let n be the no. of days
480 = n×8×4
480 = 32n
n = 480/32
n = 15
