Question “QUESTION 3 “In interval estimation, as the sample size becomes larger, the interval estimate” becomes narrower….”
QUESTION 3 “In interval estimation, as the sample size becomes larger, the interval estimate” becomes narrower. becomes wider. “remains the same, because the mean is not changing.” gets closer to 1.96. ОО QUESTION 4 “A random sample of 16 students selected from the student body of a large university had an average age of 25 years and a standard deviation of 2 years. We want to determine if the average age of all the students at the university is significantly more than 24. Assume the distribution of the population of ages is normal. Using a – .05, it can be concluded that the population mean age is” not significantly different from 24. significantly different from 24. significantly less than 24. significantly more than 24.
Answer
Solution:
3) The interval estimate can be found here:
Interval estimation : (Point estimate +- Margin error)
The margin of error shrinks as the sample size increases, which leads to a narrower Interval estimate.
Hence,
Interval estimation is based on the larger sample size. The interval estimate becomes narrower. will increase.
First option is correct.
4) Null and alternative hypotheses :
