Assumption of extrapolation
Assume that a simple random sample has been selected from a normally distribute population and test the given claim. Identify the null and alternative hypotheses, test statistic,
in a normal distribution with a mean of 85 and a STD of 5, what is the percentage of scores between 75 and 90?
If the sample size is less than 30, then we need to make the assumption that X (the volume of liquid in any cup) is normally distributed. This forces (the mean volume in the sam
