A bank sampled its customers to determine the proportion of customers who use their debit card at least once each month. A sampl
Zinaida [17]

Answer:

(0.084,0.396)

Step-by-step explanation:

The 99% confidence interval for the proportion of customers who use debit card monthly can be constructed as

p-z_{\frac{\alpha }{2}} \sqrt{\frac{pq}{n} }

p=\frac{x}{n}

p=\frac{12}{50}

p=0.24

q=1-p=1-0.24=0.76

\frac{\alpha }{2} =\frac{\0.01 }{2}=0.005

p-z_{\frac{\alpha }{2}} \sqrt{\frac{pq}{n} }

0.24-z_{0.005} \sqrt{\frac{0.24*0.76}{50} }

0.24-2.58(0.0604)

0.24-0.155832

By rounding to three decimal places we get,

0.084

The 99% confidence interval for the proportion of customers who use debit card monthly is (0.084,0.396).

a=number of adult tickets bought

300 tickest sold
total=300
a+s=300


value=rate times number of peple

student value=4s
adults value=10a
total value=1950
4s+10a=1950



a. system of equations are
s+a=300
4s+10a=1950



b. solve

s+a=300
4s+10a=1950

a+s=300
multiply by -4
-4s-4a=-1200
add to other eqaution

4s+10a=1950
<u>-4s-4a=-1200  + </u>
0s+6a=750

6a=750
divide 6
a=125


subsiute
s+a=300
s+125=300
subtract 125
s=175






a. s+a=300
