In Exercises 1-16, solve the inequality. Graph the solution<br> 1. 3y ≤ -9
murzikaleks [220]

By solving the inequality we get y\leq -3

What is graphing the inequality?

The act of illustrating which area of the number line contains values that will "satisfy" the specified inequality is known as graphing the inequality. Take a look at the first inequality, "x > -5." The numbers that can be used to substitute x in our inequality to produce a true statement can be shown on a graph of our inequality.

3y\leq -9

Dividing above equation by 3 we get,

\frac{3y}{3}\leq \frac{-9}{3}\\y\leq -3

Graph of y\leq -3 is

Therefore by solving the inequality we get y\leq -3

Fudgin [204]

Answer:

The teenagers spent 4.5 hours per week, on average, on the phone.

Step-by-step explanation:

We are given the following in the question:  

Population mean, μ = 4.5

Sample mean, \bar{x} = 4.75

Sample size, n = 15

Alpha, α = 0.05

Sample standard deviation, s = 2

First, we design the null and the alternate hypothesis

H_{0}: \mu = 4.5\text{ hours per week}\\H_A: \mu > 4.5\text{ hours per week}

We use one-tailed(right) t test to perform this hypothesis.

Formula:

t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }

Putting all the values, we have

t_{stat} = \displaystyle\frac{4.75 - 4.5}{\frac{2}{\sqrt{15}} } = 0.4841

Now,

t_{critical} \text{ at 0.05 level of significance, 14 degree of freedom } = 1.76

Since,                  

t_{stat} < t_{critical}

We accept the null hypothesis.  Thus, the teenagers spent 4.5 hours per week, on average, on the phone. The sample contradicted the organization's claim.
