Find the mesn arnd the standard devistion of Round your answers for standlard deviation to three decimai plsces tandard dewiation Do the same for a random sample of sive 75 Standard deviation?Explanation / Answer
Given, Mean, ? = 91.4
Standard deviation, s= 93.25
x? is the average daily fat intake.
For a sample size of n=24, the mean and standard deviation of x? are, respectively,
?(x) = ? = 91.4 and s(x) = s/ n0.5 = 93.25/ 240.5 = 19.035
For a sample size of n=75, the mean and standard deviation of x? are, respectively,
?(x) = ? = 91.4 and s(x) = s/ n0.5 = 93.25/ 750.5 = 10.768
Note: Mean doesn't change.
