Opposed to death penalty. Year 2000- 801 opposed out of 2565. Year 1993 337 opposed out of 1488.
I have two samples, one is 31.2% and one is 22.6%. I am trying to calculate the 95% confidence interval in context of this situation. ALso i need the formula that is used to calculate the interval and substitute appropiate numerical values into the formula. Then with this how do i find the value of (P1 with a ^ over it-P2 with a ^ over the P)So with this how do I find the 90% confidence interval for the difference between the population proportions opposed to the death penalty in the years 2000 and 1993.
This is called a one-time fling. About 10% of all adults deliberately do a opne-time fling and feel no guilt about it!
A correlation coefficient computed for n=18 and a=0.10 is r=0.692. . Using the t -test for the correlation coefficient, what are the critical values?
If the store orders three copies of the magazine, what is the mean value of the profit? (Profit = Revenue - Cost). If the store orders four copies of the magazine, is it better to order four than three copies of the magazine. Explain.

Suppose it is known that if you offer free samples o a product, at least 52% of adults are more likely to buy the product. You interview a random sample of 50 adults.
Proportion of college students who prefer drink A: (0.384, 0.424). Identify the point estimate for estimating the true proportion of college students who prefer that drink.
There are three versions of a board game released - version 1, version 2, and version 3. The versions are distributed equally and evenly among all potential sellers of board games.
Suppose we wish to test the hypothesis H0: = µ2 vs. H1: = µ≠2 We find a two sided p-value of .03 and a 95% CI for µ of (1.5, 4.0) Are these two results possibly compatible? Why or why not?
a certain model is normally distributed, with a mean of 24 mpg and a standard deviation of 1.0 mpg. find the following: The mileage rating that upper 5% of cars achieve
Find the probability value of H0:u 2.8 distribution with 10 banks giving stats of 5.7, 4.8, 6.0, 4.9, 4.0, 3.4, 6.5, 7.1, 5.3, 6.1 which gives us H1:u 5.38.
You attempt a 50 item (n = 50) true-and-false exam. You did not study for the material and your attempt to answer any item is a guess, with a 50% chance that you will get any item correct. You need a score of 30 or better to pass the exam.
Given that x and y are both positive, solve the simultaneous equations.
