A random sample of 1000 oranges showed that the mean amount of juice per orange was 7 fluid ounces, with a standard deviation of 1.6 fluid ounces. If the zscore for a particular orange was –1.5, how much juice was produced by this orange? Round approximate values to the nearest tenth of a fluid ounce.

Best ResponseYou've already chosen the best response.0The z score is standarised and tells you how many standard deviations away from the mean the orange is.

Best ResponseYou've already chosen the best response.0In a certain normal distribution of scores, the mean is 50 and the standard deviation is 4. Find the zscore corresponding to a score of 55.

Best ResponseYou've already chosen the best response.0Yes, it is normal. This orange is 1.5 standard deviations below the mean and the mean is 7 so the orange produces 71.5*1.6=4.6 fluid onces.

Best ResponseYou've already chosen the best response.1i get the 5.5 .... but whats the logic behind *zscore?

Best ResponseYou've already chosen the best response.1or is that 7(1.5*1.6)

Best ResponseYou've already chosen the best response.0\[Z=\frac{X\mu}{\sigma}\] so it tells you how many standard deviations below the mean a certain value is.

Best ResponseYou've already chosen the best response.1stats class is a little confusing to me becasue the teacher is just throwing formulas at us with no explanation ...

Best ResponseYou've already chosen the best response.0No, see the formula I posed earlier. It should be (5550)/4

Best ResponseYou've already chosen the best response.0Ah, ok, sorry. X is the number you're trying to find the Z value for, mu is the mean and sigma is the standard deviation.

Best ResponseYou've already chosen the best response.0but i understand it better than what the book would explain... its like 10 pages explain that formula

Best ResponseYou've already chosen the best response.0Remember, the z score just tells you how many standard deviations away from the mean a value is. So, say I had a mean of 50, and an SD of 2, if I was trying to find the z score of 56, it would be 3 because 56 is 3 standard deviations from the mean.
