The mean grade in this class last semester was 78.3, and the variance was 34.6 . The distribution of grades was unimodal and symmetrical.. determine how many students are likely to fail the class (<60), and how many students are likely to get a “A” (>90),...

Analyze data to determine whether or not you think there is a relationship between height and ability to lift weights (at least as measured by the bench press). 1- Compute a linear regression line to fit this data, also2- compute the correlation coefficie...

So would I do this? 60-78.3/5.882 and 90-78.3/5.882 and multiply my answer by 60? meaning I am multiplying the z-score by 60 to find the percentage/probabitlity?

Anyone?

still stuck on this...
