sample 2:

n2: 200

p2: .32

What is the point estimate of the difference between the two population proportions (to 2 decimals)?

Develop a 90% confidence interval for the difference between the two population proportions (to 4 decimals).

Develop a 95% confidence interval for the difference between the two population proportions (to 4 decimals).

(1 point) Given the following data set, let xx be the explanatory variable and yy be the response variable.

You forecast a company's dividends for the next four years. In Year 1, you expect to receive $1.00 in dividends. In Year 2, you expect to receive $1.10 in dividends. In Year 3, you expect to receive $1.20 in dividends. In Year 4, you expect to receive $1.30. After Year 4, dividends are expected to grow at 2%. The rate of return for similar risk common stock is 7%. What is the current value of this company's stock?

It sampled 40 customers in San Francisco and 50 customers in San Diego to assess potential demand.

On a scale of 1-7 (7 = very likely to buy), San Diego customers had a mean of 3.5 with a standard deviation of 1.1. SF customers had a mean of 4.1 with a standard deviation of 2.3.

Are these markets statistically different?

1.Compute standard error

2.Compute t-calc  

3.Compare |t-calc| to 1.96 (95% confidence in our results) and 2.58 (99% confidence)

4.If |t-calc| > 1.96, reject the null with 95% confidence

●

Standard error for 2 means (sxs_x ̅ ) = ?12?1+?22?2√((s_1^2)/n_1 +(s_2^2)/n_2 )

T-calc for 2 means = ?1−?2??(x ̅_1-x ̅_2)/s_x ̅

2. Find the Expected Return, Variance, and Standard Deviation for a portfolio formed with Stocks 1 and 2. The Expected Return for Stock 1 is 6%, the Standard Deviation for Stock 1 is 8%, the Expected Return for Stock 2 is 16%, the Standard Deviation for Stock 2 is 21%, the Weight of Stock 1 in the portfolio is 40%, and the Correllation Coefficient between the returns on Stocks 1 and 2 is 0.68.
