BBM Bank wants to estimate the mean yearly salary. A sample of 15 employers shows that the sample means yearly salary to be 787 with population standard deviation 21. (answer to TWO decimal places)
Based on a 90% confidence level, the lower confidence limit for the population mean is:​

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

is this part of a question or something
