camile owns a church code, a company that provides quick programming solutions. clients send crunch projects via heir webpage and the crunch bangs out the needed code as quickly as possible. camile has four programmers who do all coding. on average, a project arrives once every 5.3 hours, with a standard deviation of 5.6 hours. each project is assigned to one programmer and that programmer takes on average 19.2 hours to complete each project with a standard deviation of 19.2 hours. how many uncompleted projects does crunch code have on average at any given time

yep

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
