HURRY!!! PLEASE HELP WITH QUESTIONS!!!! WILL MAKE BRAINIEST ANSWER!!!!
steposvetlana [31]

Answer:

#1) D.$623.52  ; #2) D.17.1 ; #3) B.II and III ; #4) C.A greater availability of ATM's may make it easier to do bank transactions. Someone may choose this availability over a higher savings interest rate; #5) B.Bank E offers you a chocolate bar for filling out an application for checking and credit at the same time; #6) D.Make purchases or get cash now, and pay back the bank in monthly payments; #7) T; #8) B.Thursday ; #9) B.$1,545.83

Step-by-step explanation:

#1) 6.2% of her gross pay would be

0.062(765) = $47.43.

1.45% of her gross pay would be

0.0145(765) = 11.09

22% of the state tax withheld would be

0.22(68) = 14.96

This means her gross pay would be

765-68-47.43-11.09-14.96 = $623.52

#2) The employee benefits in addition to his gross pay would be

33500-28600 = 4900

This makes it

4900/28600 = 0.17 = 17% of his pay.

#3) Knowing where branches or ATMs are is helpful when choosing a bank.  Additionally knowledge of personal usage habits and needs will help plan where best to bank.

#4) Having more ATMs available makes banking more convenient to some customers, which is more important to some customers than high interest rates.

#5) Having a chocolate bar offered for filling out an application for checking and credit is not a good reason to examine that given bank.

#6) You cannot "borrow" against a traditional checking account and then pay it back later.

#7) An ATM withdrawal is a POS (point of sale) transaction.

#8) At the end of the day Monday, Elizabeth has

252-114.6+150 = $287.40

At the end of Tuesday she has

287.40-79.68 = $207.72

At the end of Wednesday she has

207.72-161.39 = $46.33

At the end of Thursday she has

46.33-57.40 = -11.07

This is her first overdraft.

#9) Adding together the list of items deposited we have

13.50+942.06+75.53+670.14 = 1701.23

Taking out the cash he receives gives us

1701.23-155.40 = $1545.83

Write a statement that correctly interprets the confidence interval. Choose the correct answer below. A. One has 90​% confidence
poizon [28]

Answer:

B. <em>There is a 90​% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>

Step-by-step explanation:

A. <em>One has 90​% confidence that the sample proportion is equal to the population proportion. </em>

Confidence interval gives an interval estimate, not an equality

B. <em>There is a 90​% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>

<em>Ture. </em>

<em>C.</em><em> One has 90​% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion. </em>

Also true but <em>One has 90​% confidence is not good interpretation. </em>

<em>D</em><em>. 90​% of sample proportions will fall between the lower bound and the upper bound.</em>

<em>Lower bound and upper bound is given to estimate population proportion. </em>
