How would I solve this using a TI-84 Calculator?

49 35.2 42.1 46.4 48.3 52.6 58.2 49 61.8 37.1 51.2 45.6 37 47.2 53 58.2 37 59.9 45.8 34.1 49.7 48.5 47.4 43 53.5 47 49.9 31.8 44.6 27.5

What is the mean of this data set? Round to 2 decimal places.

What is the standard deviation of this data set? Round to 3 decimal places.

What is the minimum of this data set? minimum =

What is the z-score of the minimum in this data set? z-score = Round to 3 decimal places.

Min. Mean Max.
27.50 46.39 61.80
> sd(x)
[1] 8.396663

mean=sum(all value)/number of observation

sd=sqrt( sum(all value²)/number of observation - mean²)

here minimum is 27.5

so Z-score is (27.5-46.39)/8.396663 = -2.497
