5. In a random sample of 210 students, 80% stated that they feel they made the right choice by attending CU Denver. a. Construct a 98% confidence interval for the true proportion of students who feel they made the right decision to attend CU Denver. Include the form your interval takes, the setup with the value for either za½2 or tα/2, and the resulting lower and upper bounds of the interval. b. Interpret your interval in context. 6. Revisiting question number 5, determine what size sample is needed if we wanted to estimate the true proportion of students who feel they made the right choice by attending CU Denver to within 1% using 95% confidence.
