Suppose that a manager is interested in estimating the average amount of money customers spend in her store. after sampling 36 transactions at random, she found that the average amount spent was $35.25. she then computed a 95% confidence interval to be between $31.84 and $38.66. which statement gives a valid interpretation of the interval?

a. the store manager is 95% confident that the average amount spent by the 36 sampled customers is between s31.84 and $38.66.
b. there is a 95% chance that the mean amount spent by all customers is between $31.84 and $38.66.
c. there is a 95% chance that a randomly selected customer will spend between $31.84 and $38.66.
d. the store manager is 95% confident that the average amount spent by all customers is between $31.84 and s3866

Aproduction department's output for the most recent month consisted of 8,000 units completed and transferred to the next stage of production and 5,000 units in ending work in process inventory. the units in ending work in process inventory were 50% complete with respect to both direct materials and conversion costs. calculate the equivalent units of production for the month, assuming the company uses the weighted average method.

The new york times (nov. 30, 1993) reported that “the inability of opec to agree last week to cut production has sent the oil market into turmoil . . [leading to] the lowest price for domestic crude oil since june 1990.” why were the members of opec trying to agree to cut production? so they could save more oil for future consumption so they could lower the price so they could raise the price why do you suppose opec was unable to agree on cutting production? because each country has a different production capacity because each country experiences different production costs because each country has an incentive to cheat on any agreement the newspaper also noted opec’s view “that producing nations outside the organization, like norway and britain, should do their share and cut production.” what does the phrase “do their share” suggest about opec’s desired relationship with norway and britain? opec would like norway and britain to keep their production levels high. opec would like norway and britain to act competitively. opec would like norway and britain to join the cartel.
