Assume that adults have IQ scores that are normally distributed with a mean of 100.3 and a standard deviation 23. Find the first quartile, which is the first IQ score separating the bottom 25% from the top 75%
The distribution of observed scores (in percentages) in a Chemistry final examinations were as follows: 67, 71, 73, 76, 97, 79, 82, 83, 85, 87, 88, 24, 58, 61, 88, 92, 93, 94 The lowest score on the final exam was 24. The highest score on the exam was 97. 25% of the students scored a 70 or below. 50% of the students scored above an 85.5. 75% of the students scored at most 89. We can also say that 25% of the students scored at least an 89. The lowest score on the final exam was 24. The highest score on the exam was 97. 25% of the students scored a 70 or below. 50% of the students scored above an 82.5. 75% of the students scored 89 or below.

You wish to determine if there is a positive linear correlation between the age of a driver and the number of driver deaths. The following table represents the age of a driver and the number of driver deaths per 100,000. Use a significance level of 0.05 and round all values to 4 decimal places. Driver Age Number of Driver Deaths per 100,000 60 35 55 23 22 32 40 36 40 18 38 33 80 28 37 25 Ho: ρ = 0Ha: ρ > 0 1/The p-value leads to a decision to Reject Ho Do Not Reject Ho Accept Ho 2/The conclusion is There is insufficient evidence to make a conclusion about the linear correlation between driver age and number of driver deaths. There is a significant positive linear correlation between driver age and number of driver deaths. There is a significant linear correlation between driver age and number of driver deaths. There is a significant negative linear correlation between driver age and number of driver deaths. please choose correct answer in each…

A nutritionist wrote the following summary statement for a research study: Students who major in health sciences report eating M = 4, SD = 1.5 pieces of fruit a day. (T/F) The graph of the data below accurately depicts the relationship between mean and standard deviation in a distribution for this summary statement. True False 2.5 SD = 1.5 M = 4 5.5
5. For each of the following, state whether the statement is true or false and justify your answer. a) If a distribution is skewed, it's better to give the median and IQR instead of the mean and standard deviation. b) A man is in the 96th percentile for blood pressure in his age group. This means his blood pressure is better than 96% of those in his age group. c) Two variables X and Y have a correlation of 0. This means the two have no relationship. d) For a continuous random variable X, P(X < x) = P(X < x). e) The main benefit of an observational study is we can determine causation between two variables. f) Let X be the time until a car arrives at a stop sign. Then we can model X as X * Ga(r,2) for some r and 1.
