IQ scores are normally distributed with standard deviation o= 15 points. You wish to determine the mean IQ of all students in Matiyaga National High School by taking a random sample of 16 students. 16. The general weighted average (GWA) of the Grade 11 applicants for admission in ASHS over the past 6 years has been consistently μ = 92.78. This year a sample data of the applicant's GWA are 98, 89, 92, 95, 90, 97 and 93. 17. This distribution is used to determine the probability of an event by transforming the mean of the sample to an approximately standard normal variable if the population variance is known and sample size is greater than 30. a. t-Distribution c. Z-Distribution b. Chi-Square Distribution d. Pearson Correlation Coefficient 18. This distribution is used to estimate population parameters when the population variance is unknown, and the sample size is less than 30. a. Z-Distribution c. t-Distribution b. Chi-Square Distribution d. Pearson Correlation Coefficient 19. If the mean of the sampling distribution of the mean is 6.5, which of the following statements best describe the population mean? a. The population decreases by 6.5. b. The population is greater than 6.5.
