Answer number 8 only
C. When the sample size is considered small. D. When the sample size is sufficiently large. 7. In the estimation of a parameter using the t-distribution, is it possible to replace the population standard deviation, o by the sample standard deviation, s? A. No, because the given sample size is small B. No, because o and s differ by a significant amount C. Yes, because o is unknown and s is a good estimator of o. D. Yes, because o is equal to s when we are estimating parameters 8. What will be the effect on the t distribution curve when we replace o by s? A. The t-distribution curve will become bell-shaped. B. The t-distribution curve will be symmetrical to zero. C. The t-distribution curve will be the same as the normal curve. D. The t-distribution curve will have a lower peak and thicker tails. For numbers 9 to 11, The principal of Mapayapa Integrated National High School claimed that the average salary of their teachers is P24, 000 per month. A random sample of 15 teachers in the school has a mean of P23, 220, and a standard deviation of P400. 9. Identify the population mean. A. P24,000 B. P23,220 C. P400 D. 15 10.
