Here are the returns on two stocks.

Required:

a-1. Calculate the variance and standard deviation of each stock.

a-2. Which stock is riskier if held on its own?

b. Now calculate the returns in each month of a portfolio that invests an equal amount each month in the two stocks.

c. Is the variance more or less than halfway between the variance of the two individual

For a normally distributed population with a mean of 450 and standard deviation of 20 answer the following questions.

BLANK #1: What is the probability of finding a value below 411.2? (ANSWER IN DECIMAL FORM TO 4 DECIMAL PLACES)

BLANK #2: What percent of values are above 476.6? (ANSWER AS A PERCENT TO 2 DECIMAL PLACES...INCLUDE PERCENT SIGN WITH ANSWER)

BLANK #3: The bottom 20% of observations are below what value? (ANSWER TO 2 DECIMAL PLACES)

BLANK #4: What value would you expect to find the top 10% above? (ANSWER TO 2 DECIMAL PLACES)

Calc24isafamousmathgame. Now w would like to implement an advanced Calc24 calculator. Given n integers, you need to verify whether 24 can be deduced with these numbers and four basic operators: ‘+’. ‘-’, ‘*’ and ‘/’. Note that every number can only be used once. Input The first line with two integers: n,t , where n denotes the number of integers in each group, t indicates the total number of groups that you need to verify. In following t lines, each represent n integers in that group. Output will be t lines. Each line prints either true or false, indicating whether 24 can be deduced from the corresponding line of input.

Write a program sequence that will test the byte STATUS and branch to ROOTINE_1 if bit 1, 2 or 4 is 1. Otherwise, it is branch to ROUTINE_2 if both bits 1 and 3 are 1 and to ROUTINE_3 if both bits 1 and 3 are 0. In all other cases it is to exeute ROUTINE_4. Assume that the routines are more than 128 bytes long. Also give a flowchart of the sequence.

Answer each question completely. Copy and Paste the SPSS output into the word document for the calculations portion of the problems, highlighting correct answers. (Please remember to answer the questions you must interpret the SPSS output).

1. A researcher is interested to learn if there is a linear relationship between the hours in a week spent exercising and a person’s life satisfaction. The researchers collected the following data from a random sample, which included the number of hours spent exercising in a week and a ranking of life satisfaction from 1 to 10 ( 1 being the lowest and 10 the highest).

1. Find the mean hours of exercise per week by the participants.
2. Find the variance and standard deviation of the hours of exercise per week by the participants.
3. Run a bivariate correlation to determine if there is a linear relationship between the hours of exercise per week and the life satisfaction. Report the results of the test statistic using correct APA formatting.
4. Run a linear regression on the data. Report the results, using correct APA formatting. Identify the amount of variation in the life satisfaction ranking that is due to the relationship between the hours of exercise per week and the life satisfaction (Hint: the R² value)
5. Report a model of the linear relationship between the two variables using the regression line formula.

An experiment is to flip a coin until a head appears for the first time. Assume the coin may be biased, i.e., assume that the probability the coin turns up heads on a flip is a constant p (0 < p < 1). Let X be the random variable that counts the number of flips needed to see the first head.

(a) Let k ≥ 1 be an integer. Compute the probability mass function (pmf) p(k) = P(X = k).

(b) If p = 1/3 compute P(2 ≤ X < 4) and P(1 < X < 3).

(c) If p = 1/3 compute P(X > 2).

(d) If p = 1/2 compute P(X is even).
