9) The national average SAT score (for Verbal and Math) is 1028. The distribution of the SAT score is a normal with. If the top 1% of the students will receive a $400 scholarship, what is the minimum score a student would need to score to receive the reward? 10) The average charitable contribution itemized per income tax return in Pennsylvania is $792. Suppose that the distribution of contributions is normal with a standard deviation of $103. Find...
The national average SAT score is 1028. If we assume a normal distribution with a standard deviation of 92. What is the probability that a randomly selected score is less then 1100
Us the following means and standard deviations: for ACT, µ=21, σ=3 and for SAT, µ=500, σ=100. (a) You take the ACT test and the SAT test. You get a 24 on the ACT and a 660 on the SAT. The college that you apply to only needs one score. Which do you want to send them (that is, which score is better: 24 or 660)? Why? (b) What is the probability of having an ACT score of 20 or less?...
the national average SAT score (for Verbal and Math) is 1028. Suppose that nothing is known about the shape of the distribution and that the standard deviation is 100. If a random sample of 200 scores were selected and the sample mean were calculated to be 1050, would you be surprised? Explain.
The national average SAT score (for Verbal and Math) is 1028. Suppose that nothing is known about the shape of the distribution and that the standard deviation is 100. If a random sample of 200 scores were selected and the sample mean were calculated to be 1053. Assume that the sample is taken from a large population and the correction factor can be ignored.
Assume that all SAT scores are normally distributed with a mean µ = 1518 and a standard deviation σ = 325. If 100 SAT scores (n = 100) are randomly selected, find the probability that the scores will have an average less than 1500. TIP: Make the appropriate z-score conversion 1st, and then use Table A-2 (Table V) to find the answer. Assume that all SAT scores are normally distributed with a mean µ = 1518 and a standard deviation...
The national average SAT score (for verbal and math) is 1028. Suppose that nothing is known about the shape of the distribution and that the standard deviation is 100. Round the final answer to four decimal places and intermediate z-value calculations to two decimal places Source: New York Times Almanac. Part 1 out of 2 If a random sample of 245 scores was selected, find the probability that the sample mean is greater than 1041. Assume that the sample is...
(1 point) The scores of students on the SAT college entrance μ-544.6 and standard deviation σ-25.3 (a) What is the ANSWER: that a single student randomly chosen from all those taking the test scores 548 or higher? For parts (b) through (d), consider a simple random sample (SRS) of 35 students who took the test. b) What are the mean and standard deviation of the sample mean score , of 35 students? The mean of the sampling distribution for is:...
10. The population average for SAT score is 1020, with a population standard deviation of 100 a. What is the standard deviation of the distribution of , if many samples of size 64 is selected b. What is the probability that a random sample of 64 students will provide a sample mean SAT score within 10 points of the population mean?
Scores of the Math portion of the SAT (SAT-M) are known to have a national mean μ=500 and standard deviation σ=100. A random sample of n=400 high-school seniors was chosen and their average SAT-M score was found to be x̅=522. Would this finding surprise you? A, Yes, since an average of 522 is more than 4 standard deviations above 500. B. Yes, since an average of 522 is larger than 500. C. No since an average of 522 is less...
