Answer:

  1. 2,600 textbook.
  2. 1,908 textbooks.

Explanation:

1. The equation is based on the past four years so in calculating the time period for Quarter 4 next year, the time period is:

t = (4 * 4 periods) + 4 periods next year

t = 20

Sales forecast is therefore:

= 2,120 + 24t

= 2,120 + 24 * 20

= 2,600 textbooks

2. The time period will be:

t = (4 * 4 periods) + 1 quarter

t = 17 quarters

Sales forecast:

= 2,120 - 620 + 24t

= 2,120 - 620 + 24 * 17

= 1,908 textbooks.

Suppose that a manager is interested in estimating the average amount of money customers spend in her store. After sampling 36 t
densk [106]

Answer:

The store manager is 95% confident that the average amount spent by all customers is between $ 31.84 and $ 38.66.

Explanation:

In statistics, a confidence interval is the probability that the parameter of a population lies between two set of values when a random sample of the population is drawn for a specific percentage of times. This means that the confidence interval is formed about the whole population not the sample from which it is calculated.

The probabilities of a confidence interval can take any number, but 95% and 99% confidence level that are usually used.

It should be noted that, for example, 95% confidence level implies that there is a 95% chance that the true mean of the population lies within the calculated confidence interval.

Therefore, the statement which gives a valid interpretation of the interval in the question is the first one which states that "the store manager is 95% confident that the average amount spent by all customers is between $ 31.84 and $ 38.66."

I wish you the best.
