Over the past three years, Shoprite Supermarket has observed the following distribution of modes of payment in the express lines: Cash (C) 41%, Cheques (Ck) 24%, Credit cards (D) 26%, and other (N) 9%. In an effort to make express checkout more efficient, Shoprite has just begun offering a discount for cash payment in the express checkout line. The table below presents the distribution of modes of payment for a sample of 500 express-line customers after the discount went into effect. Suppose you must test the hypothesis at 10% level of significance that the distribution of modes of payment in the express checkout line changed after the discount went into effect. Mode of payment Cash Checks Credit cards Other Number of customers 240 104 111 45 The conclusion will be a) Since 2-10.886 is not greater than and conclude that the distribution of modes of payment in the express checkout line changed after the discount went into effect. X =6.251, we then reject null hypothesis at 10% level of…
The American Association of Individual Investors (AAII) conducts a weekly survey of its members to measure the percent who are bullish, bearish, and neutral on the stock market for the next six months. For the week ending March 27, 2019, the survey results showed 33.2% bullish, 39.6% neutral, and 27.2% bearish. Assume these results are based on a sample of 300 AAII members. a. Over the long-term, the proportion of bullish AAII members is 0.385. Conduct a hypothesis test at the 5% level of significance to see if the current sample results show that bullish sentiment differs from its long-term average of 0.385, What are your findings? Ho: p - Select your answer- H: p- Select your answer - p-value: (to 4 decimals) We - Select your answer - that bullish sentiment differs significantly from its long-term average of 0.385. b.

Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.A sample of 58 stocks traded on the NYSE that day showed that 21 went up.You are conducting a study to see if the proportion of stocks that went up is is significantly more than 0.3.

Westminster Financial has released a summary of investor and investment package information from the past fiscal year. During this time, Westminster provided a choice among 12 pre-designed investment packages. The investment packages were classified according to two variables: riskiness of investment package chosen ("Risky", "Moderate/mixed", and "Conservative") and age of investor ("Under 35", "35-49", or "50+"). Suppose that we're interested in the possible relationship between the age of the investor and the riskiness of the investment package the investor chose. The following contingency table gives a summary of the information released by Westminster regarding age and riskiness of investment package for 150 investors. In the cells of the table are the respective observed frequencies, and three of the cells also have blanks. Fill in these blanks with the frequencies expected if the two variables, riskiness of investment package chosen and age of investor, are independent. Round…
