optical disk system prototype

6–73. Sony’s new optical disk system prototype tested and claimed to be able to record an average of 1.2 hours of high-definition TV. Assume n = 10 trials and C=

0.2 hour. Give a 90% confidence  interval.

6–74. The average customer of the Halifax bank in Britain (of whom there are 7.6 million) received $3,600 when the institution changed from a building society to a bank. If this is based on a random sample of 500 customers with standard deviation

= $800, give a 95% confidence interval for the average amount paid to any of the 7.6 million bank customers.

6–75. FinAid is a new, free Web site that helps people  obtain  information  on 180,000 college tuition aid awards. A random sample of 500 such awards revealed that 368 were granted for reasons other than financial need. They were based on the applicant’s qualifications, interests, and other variables. Construct a 95% confidence interval for the proportion of all awards on this service made for reasons other than financial need.
