Question

This part of your analysis looks at condos that do NOT have a river view and have PMI. Find the appropriate variable in the data set. (You may have to widen the columns to see the entire variable name. To do so, click on the vertical line between the two variable names and drag it to make the column wider. Repeat as necessary.) To check if the sampling distribution is normal, which of the following would you check? Pick the BEST choice.

• That p≥30p≥30
• That n≥30n≥30
• That nˆp≥10np^≥10 and n(1−ˆp)≥10n(1-p^)≥10
• That np≥10np≥10 and n(1−p)≥10n(1-p)≥10
• That the histogram is bell-shaped and symmetrical
• None of the above

Compute the 89% confidence interval for the proportion of those condos without a river view that have PMI. If you don't have enough information to compute the confidence interval, enter "DNE" in both boxes below.
