Answer:

$18.74

Explanation:

the margin of error for a 95% confidence level = Z x (σ / √n)

  • Z for a 95% confidence level = 1.96
  • standard deviation (σ) = $160
  • sample size (n) = 280

the margin of error for a 95% confidence level = 1.96 x ($160 / √280) = 1.96 x ($160 / 16.733) = 1.96 x $9.56 = $18.74

You determined the following information for Big Rapid's Supplies: It has a receivables turnover rate of 23.5 a payables turnove
wlad13 [49]

Answer:

35 days

Explanation:

Receivables turnover rate = 23.5

Payables turnover rate = 12.5

Inventory turnover rate = 19.15

Length of firm's operating cycle :

(Days sales in inventory + average collection period)

Days' sales in inventory = (365 days / inventory turnover ratio)

Days' sales in inventory = (365 / 19.15)

Days's sales in inventory = 18.717 days

Average collection period : (365 / accounts receivable turnover ratio)

Average collection period = (365 / 23.5)

Average collection period = 15.531

(18.717 + 15.531)

= 34.248

= 35 days
