2. A researcher wants to measure the job satisfaction levels of the employees of two fast food company located in Manila. The researcher has used a questionnaire consisting of ten questions related to job satisfaction levels of the employees. The researcher has used a rating scale from 1 to 4 where 1 is the lowest score and 4 is the highest score. So, a maximum score of 40 and a minimum score of 10 can be obtained. The researcher has randomly selected 15 employees from the first company and 17 employees from the second company. The scores obtained from these employees are given below: First Company: 32 40 31 33 32 30 30 32 31 32 34 32 38 32 28 Second Company: 25 28 23 27 24 26 27 22 25 26 34 25 23 22 29 27 24 Taking 5% as the alpha level, examine the significant difference in terms of job satisfaction level between the employees of the two companies.
You're a sociologist studying whether grocery prices are different in the inner cities than they are in the suburbs. To investigate this, you pick a random set of items (a basket of goods), and then send shoppers to buy these items at an inner city (IC) grocery, and also at a suburban (SU) grocery. You pick 27 different baskets of goods, so your secret shoppers buy 27 baskets, once at the inner city store, and once at a suburban store. The data is given in the dataset named "ICvSU_2799.xls", which you can find in data folder under Course Documents. Prices could be higher in the inner city because of discrimination, or they could be higher in the suburbs because of the greater disposable income. Use Excel to test the research hypothesis that inner city prices are different than the suburb's prices. The null hypothesis is that inner city prices are equal to suburban prices. You test at the alpha = 0.01 significance level. What do you conclude? Are prices the same? Who has higher…

In a survey, it was found that 80% of adults operate the flusher of toilets in public restrooms with their foot. (a) If 300 adults are randomly selected, how many would we expect to flush toilets in public restrooms with their foot? (b) Would it be unusual to observe 255 adults who flush toilets in public restrooms with their foot? (a) We would expect (Type a whole number.) adults to flush toilets in public restrooms with their foot. (b) Would it be unusual to observe 255 adults who flush toilets in public restrooms with their foot? Choose the correct answer below. O A. Yes, because 255 is greater than u + 2o. O B. No, because 255 is greater than u + 20. O C. Yes, because 255 is between u - 20 and u+ 20. O D. No, because 255 is less than u- 20. O E. No, because 255 is between u -20 and u+ 20.
