Asimple random sample of size n is drawn from a population that is known to be normally distributed. the sample variance, s squareds2, is determined to be 11.611.6. complete parts (a) through (c). (a) construct a 90% confidence interval for sigma squaredσ2 if the sample size, n, is 20. the lower bound is 7.317.31. (round to two decimal places as needed.) the upper bound is 21.7921.79. (round to two decimal places as needed.) (b) construct a 90% confidence interval for sigma squaredσ2 if the sample size, n, is 30. the lower bound is 7.907.90. (round to two decimal places as needed.) the upper bound is 1919. (round to two decimal places as needed.) how does increasing the sample size affect the width of the interval? the width does not change the width increases the width decreases

Yowell company granted a sales discount of $360 to a customer when it collected the amount due on account. yowell uses the perpetual inventory system. which of the following answers reflects the effects on the financial statements of only the discount? assets = liab. + equity rev. − exp. = net inc. cash flow a. (360 ) = na + (360 ) (360 ) − na = (360 ) (360 ) oa b. na = (360 ) + 360 360 − na = 360 na c. (360 ) = na + (360 ) (360 ) − na = (360 ) na d. na = (360 ) + 360 360 − na = 360 na

Which of the following statements is true of unsought products? as compared to convenience products, unsought products are purchased more frequently. unsought products are consumer products and services that customers usually buy frequently, immediately, and with minimal comparison and buying effort. a life insurance policy is an example of an unsought product. unsought products have strong brand identification for which a significant group of buyers is willing to make a special purchase effort. unsought products are those products purchased for further processing or for use in conducting a business.
