a deposit of $1,644.50;checks written for $190, $45, and $7.50;  and debit card transactions for $30, $5.59, $7.20, and $21.30.

amount deposited = 1644.50

debit card transactions for $30, $5.59, $7.20, and $21.30.

We add all the debit card transactions

30 + 5.59 + 7.20 + 21.30 =64.09

checks written for $190, $45, and $7.50

Add all the check written amounts

190 + 45 + 7.50=242.5

To find ending balance , we subtract the debit card transactions and check written from the deposit amount

1644.50 - 64.09 - 242.5 = 1337.91

$1,337.91 is the ending balance for this time frame

The 2.88 minutes have to reduce the standard deviation to increase the efficiency.

According to the statement

we have given that the duration of the trip is 2 hours and 15 minutes. And we have to how much standard deviation be reduced to increase the operational efficiency.

So, For this purpose, we know that the

Let X be the time taken to reach the resort. Then it is  given that the

N (μ , σ).

Here μ is 2 hours then

μ  = 2*60 = 120 minutes.

And

Let σ be the reduced standard deviation such that new distributions becomes N (μ , σ)

Then P ( x <135)

here 135 is the minute format of 2 hours and 15 min.

So,

P ( x <135) = 0.95

And

P [ (x -120 / σ) < (135 -120 / σ)] = 0.95

P [ Z < ( 15 / σ)] = 0.95

And after solving it the

σ = 9.22 min.

i.e. 12 - 9.22 = 2.88 min.

So, The 2.88 minutes have to reduce the standard deviation to increase the efficiency.
