A stratified sample is sometimes recommended when Multiple Choice   the sample size is very large.   the population is small compared to the sample.   distinguishable strata can be identified in the populations.   the population is spread out geographically.

Use the same scales to construct modified boxplots for the pulse rates of males and females from the accompanying data sets. Identify any outliers. Use the boxplots to compare the two data sets.

Summarize the effect different kinds of outliers can have on a data set in terms of how we interpret whether we have a good model or not.

The length of fish were measured at 3 different lakes.  Lake 1:  3.5, 4.2, 6.1, 5.2 Lake 2: 3.1, 3.2, 4.3, 2.1 Lake 3: 5.6, 7.1, 4.4, 4.1, 6.2 Is there evidence to suggest that the average length is not the same at all 3 locations? Group of answer choices There is not evidence to suggest the average length of fish is different at one of the lakes. There is evidence to suggest that the average length is different at one of the lakes.   Enter the test statistic (to 4 decimal places)
