Q1. In a game of chance a number of draws are placed with replacements from a box of tickets, 500 of these tickets are labeled -1 and 450 of these tickets are labeled 1 and the winnings are equal to the sum of draw. determine whether 50 draws or 500 draws are more likely to maximize your winnings, briefly justify your answer.
Q2. Determine whether the following statement is true or false, and explain briefly. if a simple random sample is taken from a population of registered U.S voters, the percentage of republicans in the sample must be within 1 SE of the percentage of republicans in the population.
Q3. 200 draws are made with replacement from a box of numbered tickets. these tickets are labeled either -2 or3. is it possible for the expected value of the sum to be 50. justify your answer.
To test whether there is any association between two variables using Chi-Square test for independence.
for a certain river suppose the drought length y is the number of consecutive time intervals in which the water supply
The Smoky Bear Trucking Company claims the average weight of a fully loaded moving van is 12,000 lb. The highway patrol decides to check this claim.
A fast-food restaurant sells hamburgers and chicken sandwiches. On a typical weekday, the demand for hamburgers is normally distributed with a mean 313 and a standard deviation 57; the demand for chicken sandwiches is normally distributed with a m..
Suppose the mean cannot be adjusted but the standard deviation can be reduced. What maximum value of the standard deviation would make 90% of the parts acceptable to the consumer? (Assume the mean to be 1.012)
A survey of 30 adults found that the mean age of a person's primary vehicle is 5.6 years. Assuming the standard deviation of the populaiton is 0.8 year, find the 99% confidence interval estimate for the population mean.
State the decision rule and sketch it. (c) Find the test statistic. (d) Make a decision. (e) Use Excel to find the p-value and interpret it.
Simple Linear Regression
We code middle-aged Americans as 1 and senior citizens as 0, the logistic regression model for senior citizens
For the following data set, indicate whether the shape of the distribution is normal, positively skewed, or negatively skewed. Provide evidence for your answer by calculating the mean, mode, and median.
The 99% confidence interval estimate for a population variance when a sample standard deviation of 12 is obtained from a sample of 10 items is:
