Which of the following samples taken from the sample 7, 27, 43, 49, 52, 60 could be a bootstrap sample?

A random sample taken with replacement from the original sample and is the same size as the original sample is known as a:

Suppose we have the following five number summary: Min = 6        Q1 = 11     Median = 12        Q3 = 14    Max = 19 Then, according to the fence rule formula: [LF = Q1 – 1.5(IQR) and UF = Q3 + 1.5(IQR)]:

Identify the appropriate parameter to conduct inference on based on the description of the survey/experiment conducted. Will humans swim faster or slower in syrup?  Twenty swimmers each swam a specified distance in a water-filled pool and in a pool in which the water was thickened with food grade guar gum to create a syrup-like consistecy.  Velocity, in meters per second, was recorded.  The order of the substance was selected randomly and each swimmer swam in both substances.

The width of the confidence interval for a single proportion gets narrower (i.e., smaller) when:

A random sample of 100 bottles of water was collected.  From the sample, the mean ounces was calculated to be 16.91.  In addition, the sample standard deviation was calculated to be 0.12.  Which of the following is true about these values?

Which of the following values can be a probability?

The objective of statistical inference is to:

Suppose two sections of the same class take the same exam and produce the results shown in the following histograms.  Which section had a higher standard deviation on the exam and why?

The following scatter plot includes data on 51 lakes in Florida.  The variables being displayed are Alkalinity (concentration of calcium carbonate in mg/L) and AvgMercury (average mercury level for a sample of fish from each lake).    Which of the following choices is correct in terms of checking the conditions necessary to use the t-distribution for inference on the population slope?
