Answer:

Estimate of the standard error of the mean = 0.38 lb

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = 10.87 lb

Sample size, n = 131

Standard deviation, σ = 4.31 lb

We have ti find the estimate of the standard error of the mean.

Formula for standard error:

$S.E= \dfrac{\sigma}{\sqrt{n}}$

Putting values, we get,

$S.E = \dfrac{4.31}{\sqrt{131}} = 0.3766 \approx 0.38$

0.38 lb is the standard error of the mean.

for a two week period, john and amanda had the following transactions occur to their cheking account: a deposit of $1,644.50;che

QveST [7]

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
