Step 1

The null and alternative hypothesis is given below:

From the given information, the population proportion (*p*) is 0.44 and the claim of the test parents attitudes toward the quality of education have changed or not.

The null hypothesis is,

H_{0}: *p* = 0.44

The null hypothesis is,

Ha: *p* ≠0.44

Step 2

The 95% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed is obtained below:
