Question

In the week before and the week after a holiday, there were 10,000 total deaths, and 4963 of them occurred in the week before the holiday. a. Construct a 95% confidence interval estimate of the proportion of deaths in the week before the holiday to the total deaths in the week before and the week after the holiday.

b. Based on the result, does there appear to be any indication that people can temporarily postpone their death to survive the holiday?

A clinical trial was conducted to test the effectiveness of a
drug for treating insomnia in older subjects. Before treatment, 16
subjects had a mean wake time of 101.0 min. After treatment, the
16 subjects had a mean wake time of 79.7 min and a standard
deviation of 23.9 min. Assume that the 16 sample values appear to
be from a normally distributed population and construct a 95%
confidence interval estimate of the mean wake time for a population
with...

A clinical trial was conducted to test the effectiveness of a
drug for treating insomnia in older subjects. Before treatment, 25
subjects had a mean wake time of 105.0 min. After treatment, the
25 subjects had a mean wake time of 81.6 min and a standard
deviation of 23.9 min. Assume that the 25 sample values appear to
be from a normally distributed population and construct a 95%
confidence interval estimate of the mean wake time for a population

1. After the last frost, 189 apples were picked randomly and 43
were found to be not fit for sale.
a. Construct a 95% confidence interval for the population
proportion of unsaleable apples.
b. How large a sample should be taken to estimate the proportion of
unsaleable apples to
within 2% of population proportion, using:
i:p*=43/189 ii. P*=1/2 ?

A clinical trial was conducted to test the effectiveness of a
drug for treating insomnia in older subjects. Before
treatment,
23 subjects had a mean wake time of 101.0min. After treatment,
the 23 subjects had a mean wake time of 76.6
min and a standard deviation of 22.9min. Assume that the 23
sample values appear to be from a normally distributed population
and construct a
95% confidence interval estimate of the mean wake time for a
population with drug treatments....

During a period of 11 years 696 of the people selected for grand
jury duty were sampled, and 71% of them were immigrants. Use the
sample data to construct a 99% confidence interval estimate of the
proportion of grand jury members who were immigrants. Given that
among the people eligible for jury duty, 67.9% of them were
immigrants, does it appear that the jury selection process was
somehow biased against immigrants?
