A whale-watching company noticed that many customers wanted to know whether it was better to book an excursion in the morning or the afternoon.
To test this question, the company recorded the number of whales seen in the
morning and afternoon on 15 randomly selected days over the past month,
calculated differences between the observations in each pair (afternoon
minus morning), and then constructed a 95% confidence interval for the true
population mean difference.
What conclusion can you draw from the 95% confidence interval
(1.507, 1.307) for (8-4), the population mean difference?

(co 3) the times that customers spend in a book store are normally distributed with a mean of 39.5 minutes and a standard deviation of 9.4 minutes. a random sample of 25 customers has a mean of 36.1 minutes or less. would this outcome be considered unusual, so that the store should reconsider its displays? no, the probability of this outcome at 0.035, would be considered usual, so there is no problem yes, the probability of this outcome at 0.035, would be considered unusual, so the display should be redone no the probability of this outcome at 0.359 would be considered usual, so there is no problem yes, the probability of this outcome at 0.965 would be considered unusual, so the display should be redone
