- You observe a sample of five numbers between 0 and 10. Their median is 5 and their mean is 5. What is the maximum and minimum possible variance of the numbers? (No formal calculation or proof is expected. Please explain your reasoning in one to two sentences and report the 5 numbers that give you the lowest variance and the 5 numbers that give you the highest variance.)arrow_forwardWe want to compare cholesterol levels between men and women, so we collect a sample of 20 women and 30 men. The group of men in our sample have a mean of 240.0 with standard deviation 35.0, and the women have a mean of 210.0 with standard deviation 30.0. If we reject the null hypothesis, then what is our conclusion? Group of answer choices The mean cholesterol levels are the same between men and women The mean cholesterol levels are different between men and womenarrow_forwardGiven a normal population with mean = 39 and variance = 16, what is the probability of obtaining an observation greater than 42?arrow_forward
- A dentist hypothesizes that the average time a child spends brushing their teeth is less than 60% of the suggested time brushing their teeth in the morning. The appropriate hypothesis test is a left tailed test for a population mean. false truearrow_forwardQUESTION 5 A bag contains 3 red and 2 orange balls. You pick five balls from the bag without replacement. What is the probability that you will get 3 red and 2 orange ball?

O 0.15 O 0.16 O .68 O.10 QUESTION 8 We found the correlation coefficient for the comparison between height and weight in babies to be -0.12. That means O correlation is strong O the taller the baby, the heavier the baby O the taller the baby, the lighter the baby O Height and weight of babies are independentarrow_forwardTrue or False: µ is the population mean Select one: True Falsearrow_forward
- Mensa requies a test score to be in the top 2%. The test has a mean of 100 and Std. Dev. of 15.and scores are normally distributed. If 4 subjects take the test and they have a mean of 132 but the individual scores are lost, can we conclude that all 4 of them are eligible for Mensa?arrow_forwardSuppose you did an experiment with 3 groups and 16 subjects per group. The sample variances in the three groups were 14, 16, and 18. Using Tukey's test to compare the means, what would be the two-tailed probability for a comparison of the first mean (14) with the last mean (18)?arrow_forwardOne fair coin is tossed 25 times, let X be the number of getting heads out of those 25 tossing experiments.
