Step 1

Hello there! I see that there are more than 3 sub parts in the question. According to our polocies can answer only three sub parts. So kindly find the attached solution for a, c, d (which went wrong in file shared). Kindly make a new request if you need help in other parts of the question.

From the data file for question is todays children be better off than parents

Total sample size = 1000

Total number of adults said yes ( who think today's children will be better off than their parents) = 240

Total number of adults who said no ( who think today's children will not be better half than their parents)  = 530

Total number of adults who said notsure = 230

Step 2

The proportion of adults who said yes = 240/1000 = 0.24

The point estimate of proportion of population of adults who think today children will be better off than their parents will be nothing but the sample proportion = 0.24.

The formula for confidence interval is shown below

we know p = 0.24 the proportion of adults said yes. n = 1000

Step 3

The Z score for 95% confidence interval can be found with reference to Z table shown below

α = 1 - 0.95 = 0.05

1 - α/2 = 1 - 0.0...
