For each variable of interest, do the following: 1. Find the mean, five-number summary, range, variance, and standard deviation. Display these numbers in a format that is easy to understand. 2. For each variable of interest, use its five-number summary to construct a boxplot. Each boxplot must be constructed horizontally, and must be accompanied by a brief descriptive paragraph that assesses whether the data appear to be symmetrical, left-skewed, or right-skewed. Construct a 95% confidence interval for the mean μ...

You are studying an invasive insect species in the USA.
Understanding where invasive species comes from can help with
management (e.g., importation of native natural enemies for
biocontrol). The graph below shows output from a STRUCTURE analysis
of 10 microsatellite markers in 50 individuals taken from the
invasive US population, and the three native countries of origin,
Spain, France, and Italy. A-1pt) How many genetic groups, or
clusters, were identified in the analysis? Assuming you’ve completely
sampled the native range...

A random variable X is said to follow a lognormal
distribution if Y = log(X) follows a normal
distribution. The lognormal is sometimes used as a model for
heavy-tailed skewed distributions.

You are curious about whether you can enhance the ability to hear differences between nonnative speech sounds when people learn a new language. You test your novel language training procedure on a group of 32 pariticipants using a pretest/posttest design. The pretest and the posttest measure performance as the number of correct trials out of 100. The data are shown on the right. Does the new language training procedure improve the perception of nonnative speech sounds? Number of correct items...

Conduct a formal hypothesis test of the claim that the mean longevity is less than 57 days. Test at significance α=0.05. Your written summary of this test must include the following: Your null and alternate hypotheses in the proper format. The type of distribution you used to construct the interval (t or normal). The P-value and its logical relationship to α (≤ or >). Your decision regarding the null hypothesis: reject or fail to reject. A statement regarding the sufficiency/insufficiency...

For each variable of interest – Percent Time Asleep and Longevity – create a grouped frequency histogram. For each histogram, use a class width of 10; use a lower limit of 0 for Percent Time Asleep and 15 for Longevity. Each histogram must include an informative title, along with correct labels for both axes. For each histogram, include a paragraph that answers each of the following questions: Is the histogram symmetric, skewed to the left, or skewed to the right?...
