Here is a sample of amounts of weight change (kg) of college students in their freshman year:
11, 4, −2, −8, where −8 represents a loss of 8 kg and positive values represent weight gained. Here are ten bootstrap samples:
{11, 11, 11, −2}, {11, −8, −2, 11}, {11, −8, 4, −2}, {4, −8, −2, 11}, {−2, −2, −2, 4}, {4, −8, 4, −8}, {11, 4, −8, −2}, {−8, 4, −8, 4}, {−8, −2, −8, 4}, {4, 11, 11, 11}.

Transcribed Image Text:9. Here is a sample of amounts of weight change (kg) of college students in their freshman year: 11, 4, -2,
-8, where - 8 represents a loss of 8 kg and positive values represent weight gained. Here are ten
bootstrap samples: (11, 11, 11, -2}, {11, −8, −2, 11}, {11, −8, 4, −2}, {4, -8, -2, 11},
{-2, -2, -2, 4}, {4, −8, 4, −8}, {11, 4, 8, -2}, {-8, 4, 8, 4}, {-8, -2, −8, 4}, {4, 11, 11, 11).
Complete parts (a) and (b) below.
a. Using only the ten given bootstrap samples, construct an 80% confidence interval estimate of the mean
weight change for the population.
