. IQ is normally distributed with a mean of 100 and a standard deviation of 15. Suppose an individual is randomly chosen. a) (3pt) Find the probability that the person has an IQ greater than 125. b) (4pt) Find the probability that the person has an IQ score between 105 and 118. c) (4pt) What is the IQ score of a person whose percentile rank is at the 75th percentile, ?75? d) (3pt) Use the information from part (c) to fill in the blanks and circle the correct choice in the following statement. ________% of the individuals (persons) have IQ score less than/more than __________ e) (4pt) “MENSA” is an organization whose members have the top 2% of all IQs. Find the minimum IQ needed to qualify for the “MENSA” organization

The number of faults over a period of time was collected for a sample of 100 data transmission lines. We want to test if the data come from a Poisson distribution.
| number of faults | 0 | 1 | 2 | 3 | 4 | 5 | >5 |
| number of lines | 38 | 30 | 16 | 9 | 5 | 2 | 0 |
(a) Assuming the number of faults for a data-transmission line, Yi , i = 1, . . . , 100, follows a Poisson distribution with parameter λ, find the maximum likelihood estimate of λ for these data.
(b) Test the hypothesis that the number of faults for a data-transmission line follows a Poisson distribution using the chi-squared test. Do we reject the null hypothesis at the 5% significance level? Hint: You should combine the observed data into several groups such that expected frequencies are greater or equal to 5 for each group.

The mass of Saturn is approximately 100 times that of the Earth, and the semimajor axis of Saturn’s orbit is approximately 10 AU.
(a) To this approximation, how does the gravitational force that the Sun exerts on Saturn compare to the gravitational force that the Sun exerts on the Earth?
(b) Which planet will experience greater acceleration? By what factor?
