Given that S<span>am's distribution of meal costs has a mean of $9 and a standard deviation of $3, this means that the range of Sam's meal cost that are within one standard deviation is given by ($9 - 3, $9 + 3) = ($6, $12).

Given that Sam </span><span>always tips the server $2 plus 10% of the cost of the meal, this means that when the cost of the meal is $9, Sam tips $2 + (0.1 x 9) = $2 + $0.9 = $2.90

Therefore, the mean of the distribution of Sam's tips is $2.90

Similarly, the </span><span>range of Sam's tips that are within one standard deviation is given by ($2 + 0.1(6), $2 + 0.1(12)) = ($2 + 0.6, $2 + 1.2) = ($2.6, 3.2) = ($2.9 - $0.3, $2.9 + $0.3)

Therefore, </span><span>the standard deviation of the distribution of Sam's tips is $0.3</span>

ivann1987 [24]

Answer:

Warranty liability $2,128

Explanation:

680 phones sold x 5% x $76 per repaired phone = $2,584 total warranty liability

6 phones were repaired during the year x $76 =  $456

remaining warranty liability = total estimated liability - money spent repairing phones during the year = $2,584 - $456 = $2,128

total outstanding warranty liability = $2,128

Since phone warranties last less than a year, the full amount should be recorded under current liabilities.
