Suppose that X is a normal random variable, with its mean of 3 and its standard deviation of 2. (a) Suppose that David is going to randomly choose a sample of 10 observations from this population. What is the probability that the sample mean of X exceeds 3.2

  0.376

Step-by-step explanation:

Given: X is a normal random variable, with its mean of 3 and its standard deviation of 2.

Sample size : n= 10

The probability that the sample mean of X exceeds 3.2 will be :

Hence, the probability that the sample mean of X exceeds 3.2= 0.376

answer: 1 2 3 6

step-by-step explanation:

1x6=6 2x3=6

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
