Find and interpret a 95% confidence interval for how the average weight changes for a one hour
increase in sleep per night.
Find and interpret a 95% confidence interval for the average weight given 6.5 hours of sleep per
night is obtained.
Transcribed Image Text:Find and interpret a 95% confidence interval for how the average weight changes for a one hour increase in sleep per night. Find and interpret a 95% confidence interval for the average weight given 6.5 hours of sleep per night is obtained.
Consider the following scenario to answer the questions below:
Researchers would like to determine, for adults, if there is a linear relationship between number of
hours of sleep obtained per night and weight (in pounds). If so, the researchers would like a model that
will estimate the weight of adults given the number of hours of sleep obtained per night. To answer the
questions, the following data was obtained:
