true because the square root is a number times itself and 4*4 is 16
Answer:

a. We get 56 heads out of 100 tosses.
We will use one sample proportion test
x = 56
n = 100



Formula of test statistic =
=
=
refer the z table for p value
p value = 0.8849

p value of part B is less than Part A because part B have 10 times the number the tosses.
<em>The answer is Ms Hernandez can bring up to 6 people to the zoo.</em>
<em />
<em>x - the number of people that she can bring to the zoo</em>
<em>The parking will cost $7: a = 7</em>
<em>Admission tickets will cost $15.50 per person: b = 15.50x</em>
<em>She can spend on parking and admission tickets $100:</em>
a + b ≤ 100
a = 7
b = 15.50x
7 + 15.50x ≤ 100
15.50x ≤ 100 - 7
15.50x ≤ 93
x ≤ 93 / 15.50
x ≤ 6
