Question

twenty years​ ago, ​% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. a recent survey found that of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. do parents feel differently today than they did twenty years​ ago? use the level of significance.

Answer 1

The p value of the test is less than the 0.01, therefore the conclusion is to reject the null hypothesis at 0.01 level of significance.

How to illustrate the information?

It should be noted that from the information given, the sample is independent and also a random sample. The standard deviation is 0.0182.

The standard deviation will be:

= ✓(0.46)(1 - 0.46)/750

= 0.0182

The test statistic will be:

= (0.2867 - 0.46)/0.0182

= -9.52

The alternative hypothesis shows that the test is two tailed and the p value is -1.645.

Therefore, the p value of the test is less than the 0.01, therefore the conclusion is to reject the null hypothesis at 0.01 level of significance.
