The randNorm function in the TI-83 was used to generate the following 50 numbers with a mean of 75 and standard deviation of 5. Use the empirical rule, a histogram, and a normal quantile plot to determine if this data could have come from a normal distribution. Explain clearly how each of these tools provide evidence for your conclusion. The data:
66, 66, 67, 68, 68, 68, 70, 70, 70, 71
71, 71, 72, 73, 73, 73, 73, 73, 74, 75
75, 75, 76, 76, 76, 77, 77, 77, 77, 77

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
