Step-by-step explanation:
2√(x-5) = 2
√(x-5) = 1
x-5 = 1
x = 6
'of' can be translated into multiply so
9/10 of 90=9/10 times 90
90=90/1
9/10 times 90/1=(9 times 90)/10=810/10=81/1 times 10/10=81
From a normally distributed population, a simple random sample of size 30 is taken. The mean of the sample is 144 and the standard deviation of the sample is 12.
Construct a 90% confidence interval for the population mean.
