Question
A-3. The daily revenue at a restaurant in London has been recorded for the past several years. Records indicate that the population mean daily revenue is £10000 and the population standard deviation is £1500. The population distribution of the daily revenues is unknow. (a) A sample is collected for the daily revenue. To study the shape of the sample mean distribution, which of the following statistical distributions for the population must we assume: A. Uniform B. Normal C. Binomial D. None of the above (b) It turns out that the population of daily revenue distribution is skewed due to holiday seasons during the year. Suppose that 100 days are randomly selected from the revenue records and the average daily revenue computed. Which of the following describes the sampling distribution of the sample means? A. Normally distributed with mean £10000 and a standard deviation of £150 B. Normally distributed with mean £10000and a standard deviation of £1500 C. Normally distributed with mean £1000 and a standard deviation of £150 D. Binomial distributed with mean £10000 and a standard deviation of £15
