Answer: The value of test statistic = -10.67

Step-by-step explanation:

Test statistic for proportion:

$z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

, where p= population proportion

n= sample size

$\hat{p}$ = sample proportion

AS per given,

p=0.94, n= 1004, $\hat{p}=0.86$

$z=\dfrac{0.86-0.94}{\sqrt{\dfrac{0.94(1-0.94)}{1004}}}\\\\=\dfrac{-0.08}{\sqrt{\dfrac{0.0564}{1004}}}\\\\=\dfrac{-0.08}{\sqrt{0.0000561752988048}}\\\\=\dfrac{-0.08}{0.00749501826581}\\\\=-10.673756509\approx-10.67$

i.e. the value of test statistic = -10.67

Paul and Cindy own different pizza shops. Paul makes 12 pizzas the first day and 6 pizzas each day after that. Cindy makes 16 pi

pishuonlain [190]

The right answer is Option C.

Step-by-step explanation:

Given,

Pizzas made by Paul on first day = 12

Pizzas made each day after that = 6

Let,

p represent the number of pizzas made after first day.

Total pizzas = 6p + 12

Number of days = 8 because first day 12 pizzas are made

Total pizzas = $6(8)+12=60$

Pizzas made by Cindy on first day = 16

Pizzas made each day after that = 4

Total pizzas = 4p + 16

Total pizzas = $4(8)+16=48$

Paul has made more pizzas after 9 days. He has made 60 pizzas.

The right answer is Option C.
