A 95% confidence interval for the proportion of students achieving a reading achievement score that is above the standard set by the teachers for a population of third grade students is (0.43, 0.49).
The margin of error of this interval is:

Group of answer choices

0.05

0.03

0.06

None of the above

0.03

Explanation:

First, you subtract the upper bound of the confidence interval by the lower bound of the confidence interval. Then, you divide that number by 2 to get the margin or error.

In this case: (0.49 - 0.43)/2 = 0.03

11:22 AM

Step-by-step explanation:

By means of a statement we can know that:

After an hour and 8 minutes, he stays 8 minutes behind

Which means that in 2 hours, it will take 16 minutes

If it is 10:30, it means that it is 6:30 hours later, that is to say 6.5.

therefore 6.5 x 8 = 52

Which means that at 10:30 the clock is 52 minutes late

So the correct time is 11:22 AM
