Suppose you do a study of acupuncture to determine how effective it is in relieving pain. You measure sensory rates for 16 subjects with the results given below.
8.6; 9.4; 7.9; 6.8; 8.3; 7.3; 9.2; 9.6; 8.7; 11.4; 10.3; 5.4; 8.1; 5.5; 6.9, 8.8
Use the sample data to construct a 95% confidence interval for the
mean sensory rate for the population (assumed normal) from which you took the data.

An important statistical measurement in service facilities (such
as restaurants and banks) is the variability in service times. As
an experiment, two bank tellers were observed, and the service
times for each of 100 customers were recorded. Do these data allow
us to infer at the 5% significance level that the variance in
service times differs between the two tellers? Estimate with 95%
confidence the ratio of variances of the two bank tellers. Teller 1

You are a manufacturer who wants to obtain a quality measure on
a product, but the procedure to obtain the measure of how well the
product works (Score 2) takes over an hour. There is an indirect
approach, which uses a different product score (Score 1) in place
of the actual quality measure. This approach takes only a minute
but also is less precise. Use a stat > linear regression >

We want to compare the
soil water content (% water by volume) of two fields growing bell
peppers.
The claim is that the two fields have different soil water
content.
Use the data below to test the hypothesis that the fields have
different soil water content.
Field 1 is in list1 and Field 2 is in list2.
We do not know whether the water content values are normally
distributed or not, but their variances are equal.
Provide your answers below....

bosses to household chores. The data were gathered through
hour-long telephone interviews with a nationally representative
