Watch demo video

Lab 10.2.1

A random sample of 25 test scores was selected from an approximately normally distributed population of test scores. The mean and standard deviation are 85 and 7 respectively.

  1. Compute the margin of error using the error_t_mean fucntion above for constructing a 90% confidence interval.
  2. Construct a 90% confidence interval using the conf_t_mean function above.
