7. What z-score value separates the highest 10% of the scores in a normal distribution from the lowest 90%? 8. Scores on the SAT form a normal distribution with a mean of μ-550 with σ 100. If the state college only accepts students who score in the top 65% on the SAT, what is the minimum score needed to be accepted? What does that z-score become if they change their criteria so that only...

2. The average earnings of male college dogs are $62,450 for men aged 25 to 34. The average earnings of female college cats with the same qualifications are $53,270. Based on the results below, can it be concluded that there is a difference in mean earnings between male and female college dogs and cats? Use a 0.01.

1. (a) Which of the following is true and which is false? If you think a statement is true, provide a proof. Disprove those you think are false by giving a counterexample (i) A probability density function never exceeds 1 (ii) Suppose X and Y are two random variables defined on the same sample space, such that X > Y. This implies Var[X > Var Y] (ii) Let Z be a standard normal random variate N(0, 1). Then Z and...

can i have a little help with these two problems,
please?
Question 34 1 pts True or False. (Determining sample size n for the purpose of estimating mean). For a fixed confidence level (1-alpha) and given population standard deviation, increasing the sampling error (SE) will lead to a larger sample size n. O False O True D Question 35 1 pts True or False. In general, large p-values support the alternative or research hypothesis. True False

For each of the following statements, identify whether the statement is true or false, and explain why. Please limit each response to no more than 2 sentences. a) The probability that a continuous random variable takes a specific value is 0. b) Statistical inference is the process of drawing conclusions about unknown statistics by using known parameters. c) The terms “histogram” and “bar graph” are synonyms. d) If two events A and B are independent, then there is no overlap...

1- True or false: a. If A is an event of a sample space with P(A)-P(AS), then P(A)-0.5 b. Under certain conditions, it is possible that the sum of the probabilities of all the sample points in a sample space is less than one P(A or B)-P(A)+P(B) P(A and B) P(A).P(B) by its own probability and then adding all the products together; that is P deviation of σ.
