The probability computed shows that point estimate of the population is 6.2%.

<h3>How to calculate the probability?</h3>

The point estimate of the population will be calculated thus:

= 62% = 62/100 = 0.62

The margin of error of the population will be:

= z value × [✓0.62 × ✓0.38 / ✓200]

= 1.96 × (0.78 × 0.61 / 14.14)

= 0.0672

Therefore, the interval estimate is 6.72%.

The community action group’s claim is not likely based on either interval estimate of the true population proportion since the interval is less than 0.45.

Hank and Debra each own two milking cows. One day, they milked their cows and compared the amount of milk the cows produced in t
drek231 [11]

Answer:

The answer to your question is  2 7/24

Step-by-step explanation:

Data

Hank's cows = 4 3/4   and  4  1/8

Debra's cows = 5 1/2  and  5 2/3

Process

1.- Convert the mixed functions to improper fractions

Hank's           (16 + 3)/4  = 19/4           (32 + 1)/8 = 33/8

Debra's          (10 + 1)/2 = 11/2              (15 + 2)/3 = 17/3

2.- Sum up Hank's milk and Debra's milk

Hank's       19/4 + 33/8 = 38/8 + 33/8 = 71/8

Debra's      11/2 + 17/3 = 33/6 + 34/6 = 67/6

3.- Subtract Hank's milk to Debra's milk

                 67/6 - 71/8 = (268 - 213)/24

                                    = 55/24

-Convert into a mixed fraction

                                2

                      24   55

                                7

                                      55/24 = 2 7/24

4.- Conclusion

Debra milked 2 7/24 more milk than Hank
