6. A state university randomly selects 500 students and finds that 375 of them say "being very well-off financially" is an important goal. a. Find the observed sample statistic. Use the proper notation (or p). (Letter) (Value) b. Verify that the sample size is large enough to use the normal distribution to construct a confidence interval for the true proportion of the population that say "being very well-off financially" is an important goal. Show calculations. C. Construct a 99% confidence interval for the proportion of the population who believe "being very well-off financially" is an important goal. Show all organized work as was done in the videos and box your final answer.
