3.0
3.5
4.0
4.5
3.0
Would it be reasonable to develop a confidence interval from these data to
show the mean number of hours of TV watched? If yes, construct an
appropriate confidence interval and interpret the result. If no, why would a
confidence interval not be appropriate?
Q.2 A manufacture of cell phone batteries wants to estimate the useful life of it's
battery (in thousand of hours.) The estimate is the be within 0.10 (100) hours.
Assume 1 95 percent level of confidence and that the standard deviation of the
useful life of the battery is 0.90 (900 hours). Determine the required sample size.
Q3.In a sample of 200 residents of Georgetown country, 120 reported they

confidence interval that proportioned of residents who believe the tax rate
