Hi can you help me answer this question. I got none, none, d, b, and d for question 1. am I correct?

Thanks :)

Question 1: (10 points) 1. (2Points) Given a population of numbers: 3, 7, 4, 6, 2, 2, 7, 3, 2. Which 2 of the following are the same? (a) average (b) range (c) SD (d) median (e) mode 2. (2Points) 225 samples of water specimens are taken from a lake at random. The sample mean alkalinity is 50.0 mg per litre and the sample standard deviation is 4.0 mg per litre. According to the Empirical rule approximately how many samples have alkalinity level between 42.0 and 58.0? (a) 75 (b) 111 (c) 125 (d) 169 (e ) none of the above 3. (2Points) Two cards are chosen at random without replacement from the following set {T, T, E, E, E}. Let A be the event that the rst card chosen is a T and let B be the event that the second card chosen is a T. Which of the following is true: (a) A and B are both independent and mutually exclusive. (b) A and B are independent but not mutually exclusive. (0) A and B are mutually exclusive but not independent. (d) A and B are neither mutually exclusive nor independent. 4. (2Points) Which statement is correct about a pvalue interpretation? The a) smaller the p value the stronger the evidence against the alternative hypothesis b) smaller the p value the stronger the evidence against the null hypothesis c) larger the p value the stronger the evidence against the alternative hypothesis d) larger the pvalue the stronger the evidence against the null hypothesis e) None of the above 5. (2Points) The proportion of students who own a cell phone on college campuses across the country has increased tremendously over the past few years. It is esti mated that approximately 90% of students now own a cell phone. Ten students are to be selected at random from a large university. Assume that the proportion of students who own a cell phone at this university is the same as nationwide. Let X i the number of students in the sample of 10 who own a cell phone. What is the standard deviation of X?: (a) 0.65 (b) 0.5 (c) 0.24 (d) 0.95
