The length of human pregnancy is known to have mean length of 268 days. a random sample of 64 pregnant women was selected and it was found that the average pregnancy length in that sample was 266 days.
which of the following is a true statement about this scenario?
1. if a different random sample of 64 pregnant women were selected, the average pregnancy length in that sample would have to be also 266 days.
2. both 268 and 266 are parameters
3. both 268 and 266 are statistics
4. 268 is a parameter and 266 is a statistic
5. the recorded sample average of 266 days is clearly a mistake. it must be 268 days just like the population mean.
