The distribution of actual weights of 8 oz. wedges of cheddar cheese produced at a dairy is normal with mean 8.1 ounces and standard deviation 0.2 ounces. a sample of 10 of these cheese wedges is selected. what is the standard deviation of the sampling distribution of the mean
a. approximately normal, mean 8.1, standard deviation 0.2.
b. approximately normal, mean 8.1, standard deviation 0.020.
c. it is not possible to tell because the sample size is too small.
d. approximately normal, mean 8.1, standard deviation 0.063.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

the probability that a bird is green (.30) is true

step-by-step explanation:

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0
