Interpretation of CI
There is 90% probability that the true mean of the population(or proportion) lies in the interval {0.347160,0.399109}
f)
Since the test statistic lies in the 90% confidence interval, hence at alpha = 0.1, we fail to reject the null hypothesis ie p = 0.5.

A random survey of medical records at many schools across the country found that, among more than 13,000 children only 97.4% had been vaccinated. Has the percentage of children vaccinated against measles decreased? Use a significance level of a = 0.05. a) Write the hypotheses. (2 points) b) Check the necessary assumptions and conditions.

A national survey indicated that the mean weight of 14-year-old
boys was 50 kilograms. In addition, the population was normally
distributed. Based on preliminary data, a researcher believes that
the average for 14-year-old boys in Maine is different from the
national average. To investigate this belief, she randomly samples
six 14-year-old boys and records their weights: 44, 47, 45, 48, 49,
and 49.
