Answer:

3/14

Step-by-step explanation:

We need to line up the fractions. 5/7 on top, 1/2 on the bottom. We need to find common denominator so, 7 x 2 (denominators) gives us 14. 14 is now the denominator we will use. Solve for numerator: Starting at bottom fraction. 2 goes into 14 7 times, 7 times original numerator (1) 35. Theres your new numerator. Now, the top fraction: 7 goes into 14 2 times. 2 x original numerator (5) = 10. Now subtract both numerators (10 - 7 = 3) Plug in the denominator and your answer is: 3/14

X/7= 3
⇒ x= 3*7
⇒ x= 21

x/7= 20
⇒ x= 20*7
⇒ x= 140

x/7= 21
⇒ x= 21*7
⇒ x= 147

x/7= 22
⇒ x= 22*7
⇒ x= 154

What would happen to the mean of the sampling distribution of p-hat if the Statistics major predicted the sampling distribution

Flura [38]

Answer:

Step-by-step explanation:

If repeated sample sizes of large sizes are taken at random, and proportion P is calculated for samples the sample mean will have a normal distribution irrespective of the original distribution.

In other words, the sample proportion will follow a normal distribution with mean = p-hat and std deviation = $\sqrt{\frac{p(1-p)}{n} }$
