Answer:1.6%

Step-by-step explanation: no of students in 2010=311

no of students in 2016=306

difference=311-306

=5

%decrease=5/311 x 100

Answer:

At least 10 hours
No more than 7 feet
At least $7.5
More than 3 players

Step-by-step explanation:

1.

20x + 100 ≥ 300
20x ≥ 200
x ≥ 200/20
x ≥ 10

At least 10 hours

2.

2(8 + x) ≤ 30
8 + x ≤ 15
x ≤ 15 - 8
x ≤ 7 feet

No more than 7 feet

3.

8x + 20 ≥ 80
8x ≥ 60
x ≥ 60/8
x ≥ 7.5

At least $7.5

4.

3(p + 3) > 18
p + 3 > 18/3
p + 3 > 6
p > 6 - 3
p > 3

Answer:

C. z = 2.05

Step-by-step explanation:

We have to calculate the test statistic for a test for the diference between proportions.

The sample 1 (year 1995), of size n1=4276 has a proportion of p1=0.384.

$p_1=X_1/n_1=1642/4276=0.384$

The sample 2 (year 2010), of size n2=3908 has a proportion of p2=0.3621.

$p_2=X_2/n_2=1415/3908=0.3621$

The difference between proportions is (p1-p2)=0.0219.

$p_d=p_1-p_2=0.384-0.3621=0.0219$

The pooled proportion, needed to calculate the standard error, is:

$p=\dfrac{X_1+X_2}{n_1+n_2}=\dfrac{1642+1415}{4276+3908}=\dfrac{3057}{8184}=0.3735$

The estimated standard error of the difference between means is computed using the formula:

$s_{p1-p2}=\sqrt{\dfrac{p(1-p)}{n_1}+\dfrac{p(1-p)}{n_2}}=\sqrt{\dfrac{0.3735*0.6265}{4276}+\dfrac{0.3735*0.6265}{3908}}\\\\\\s_{p1-p2}=\sqrt{0.00005+0.00006}=\sqrt{0.00011}=0.0107$

Then, we can calculate the z-statistic as:

$z=\dfrac{p_d-(\pi_1-\pi_2)}{s_{p1-p2}}=\dfrac{0.0219-0}{0.0107}=\dfrac{0.0219}{0.0107}=2.05$

z=2.05
