Hope you're having a good day. The answers are already given, just need to choose out of it. Your answer will surely be helpful to me.
Note: NO NEED EXPLANATION. Just need right answer from the given choices. :)

O 1.48T8 0 0.5122 0 03338 26. IQ test scores are normally distributed with a mean of 100 and a standard deviation of 15. An individuals' IQ score is found to be 110. Find the zscore corresponding to this value. * (1 Point} 21. A normal distribution with a mean of 0 and a standard deviation of 1 is called ? * (1 Point) Standard Normal Distribution Mean Normal Curve Z- score 22. What shape is a normal distribution curve? * (1 Point) Square curve Round curve Half curve Bell curve 23. Philip's standard deviation on a test is +2.5. What does this mean? * (1 Point) He did better than everyone. He did terrible. He scored 2.5 standard deviations above the average. O He'd better start studying.18. The longrun average of a random variable is called ? t (1 Point} O the expected value 0 the coefcient of determination O the mode 0 the standard deviation 19. According to the empirical rule, the bell or mound shaped distribution will have approximately 68% of the data within what number of standard deviations of the mean? * (1 Point} 0 three standard deviations 0 four standard deviations 0 two standard deviations 0 one standard deviation 20. A continuous probability distribution that is symmetrical on both sides of the mean, so the right side of the center is a mirror image of the left side. * (1 Point} O Normal Distribution 0 Normal Curve 27. The symbol u represents the -?* (1 Point) sample mean population mean significance level population standard deviation 28. Sample is a sub-set of what? * (1 Point) Distribution Population Set Data 29. Normal Distribution is also known as (1 Point) O Lagrangian Distribution Gaussian Distribution Laplacian Distribution Cauchy's Distribution15. Half of the observations in a data set are greater than the? * (1 Point} O median mode standard deviation 000 mean 16. A researcher is studying students in college in Davao City. He takes a sample of 400 students from 16 colleges. The average age of all college students in Davao City is called * [1 Point} O a statistic O a population 0 a parameter Q the median 17. If population A has a larger standard deviation than population B, which of the following is NOT true? * (1 Point} O The mean ofa sample from population Awill on average be larger than the mean ofa sample from population E. Population E- has a smaller variance than population A. O The mean of a sample of 20 from population A has a larger standard deviation than the mean of a sample of 20 from population IS. A typical observation from population A will be farther from the mean of population A than a typical observation from B will be from the mean of population 3
