18) The Pew Research Center reported in 2000 that 36% of women 40 to 44 years of age have never given birth. A random sample of 289 women aged 40-44 shows that 60 have never given birth.
a) Find the probability of the Sample Proportion being < 20.76%
b) Explain whether this probability indicates that a result like 60/289 is ‘unusual’, and that we therefore have or lack sufficient evidence to suspect that the percentage of women aged 40-44 has decreased since 2000.

In a previous poll, 36% of adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Suppose that, in a more recent poll, 378 of 1108 adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Is there sufficient evidence that the proportion of families with children under the age of 18 who eat dinner together seven nights a week has decreased?...

According to a report issued by the CDC in 2013, 66.8 % of women
40 years of age and over had a mammogram within the last two years.
An oncologist at the CDC would like to know if there has been a
change in this percentage over the last two years. A random sample
of 749 women (40 and older) is taken, and each is asked the date of
their last mammogram.

Recall in our discussion of the binomial distribution the research study that examined schoolchildren developing nausea and vomiting following holiday parties. The intent of this study was to calculate probabilities corresponding to a specified number of children becoming sick out of a given sample size. Recall also that the probability, i.e. the binomial parameter "p" defined as the probability of "success" for any individual, of a randomly selected schoolchild becoming sick was given. Suppose you are now in a different...

My Ask You C-reactive protein (CRP) is a substance that can be measured in the blood. Values increase substantially within & hours of an infection and reach a peak within 24 to 48 hours after. In adults, chronically high values have been linked to an increased risk of cardiovascular disease. In a study of apparently healthy children aged 6 to 60 months in Papua New Guinea, CRP was measured in 90 children. The units are milligrams per liter (mg/l). Here...
