Table
Number of donuts Price
1 $1.05
2 $ 2.1
3 $3.15
4 $4.2
5 $5.25
6 $6.3
10 $10.5
slope = (10.5 - 1.05) / 10 - 1
= 9.45 / 9
= 1.05
Equation
y - 10.5 = 1.05 (x - 10)
y = 1.05x - 10.5 + 10.5
y = 1.05x
For 40 donuts
y = 1.05(40)
y = $42
Answer:
95 percent confidence interval
[0.208,0.29166]
Step-by-step explanation:
First we identificate the sample proportion p = 27 /108, and we find the 95 percent confidence interval for P(population proportion) in this context the parking violations that have prior unpaid parking tickets.
Then α = 0.05 and 1 - α/2 = 0.975
Thus
The 95 percent confidence interval is
[ p ± 1.96 ]
[0.25 ± 1.96 ]
[0.208,0.29166]
