Hi, can I get help with these stats questions?

1. [3 marks] Draw a normal curve with mean 12 and standard deviation 0.7, on the curve show the X values that are 1, 2, and 3 standard deviations above and below the mean. 2. [2 mark] Draw a new normal curve with the same mean as question 1. Show where the x value of 11.6 would land. How many standard deviations is it above or below the mean? 3. [1 marks] Draw a new normal curve where you have converted the mean and standard deviation to the standard normal. Convert the x value of 12.9 to the standard normal and show this value on the normal curve. 4. [4 marks] Redraw the same standard normal curve and shade the portion of the curve where the lowest 20% of values would fall. Indicate both the standard 2 value for the lowest 20% and also find the x value that corresponds with the lowest 20%
