The number of violent cri mes committed in a day possesses a distribution with a mean of 2.8 crimes per day and a standard deviation of 4 crimes per cay. A random sample of 100 days was observed, and the sample mean number or crimes for the sample was calculated. Describe the sampling distribution of the sample means.

a.) shape unknown with mean of 2.8 and a standard deviation of 0.4
b.) approximately normal with mean of 2.8 and standard deviation of 4
c.) shape unknown with mean of 2.8 and standard deviation of 4
d.) approximately normal with mean of 2.8 and standard deviation of 0.4

step-by-step explanation:

step-by-step explanation: i dont

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
