parents who have children in grades​ K-12 if they were satisfied with the quality of education the students receive. Of the

1 comma 1451,145

​surveyed,

451451

indicated that they were satisfied. Construct a

9595​%

confidence interval to assess whether this represents evidence that​ parents' attitudes toward the quality of education have changed.

Use technology to find the

9595​%

confidence interval.The lower bound is

nothing.

The upper bound is

nothing.

​(Round to two decimal places as​ needed.)

What is the correct​ conclusion?

A.Since the interval

containscontains

the proportion stated in the null​ hypothesis, there is

sufficientsufficient

evidence that​ parents' attitudes toward the quality of education have changed.

B.Since the interval

containscontains

the proportion stated in the null​ hypothesis, there is

insufficientinsufficient

evidence that​ parents' attitudes toward the quality of education have changed.

C.Since the interval

does not containdoes not contain

the proportion stated in the null​ hypothesis, there is

evidence that​ parents' attitudes toward the quality of education have changed.

D.Since the interval

does not containdoes not contain

the proportion stated in the null​ hypothesis, there is
