A cable internet provider claims that users can download data at an average speed of 15 megabits per second (Mbps). You are a customer of this ISP, and you decide to test this claim. You perform 17 tests where you measure your connection speed (in Mbps), and you find the data below. Note that you only care if your connection speed is significantly less than advertised!
14.1, 15.0, 14.2, 15.4, 15.1, 13.7, 15.8, 13.4, 14.8, 15.2, 15.5, 13.2, 12.8, 16.0, 14.3, 14.9, 13.7
A 95% confidence interval for your mean connection speed is: Mbps to Mbps.
The p-value of the hypothesis test is:
At a 5% significance level, what would you conclude?
1. The observed data is not consistent with your ISP's claim.
2. The observed data is consistent with the ISP's claim.

The CDC publishes charts on Body Mass Index (BMI) for boys and
girls of different ages. Based on the chart for girls, the mean BMI
for 6-year-old girls is listed as 15.8 kg/m2. The data from which
the CDC charts were developed is old and there is concern that the
mean BMI for 6 year olds girls has increased.
The BMI’s from a current random sample of 50 6-year-old girls is

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....
