Choose the equation below whose axis of symmetry is x = 2.
Svetlanka [38]
The answer is <span>y = x2 − 4
if you try to factor out all of the equations given to you (ex. 0=x2+4x+2), the only equation that can be factored out is </span><span>y = x2 − 4.
</span><span>
y = x2 − 4
</span><span>0= x2 − 4
</span>0=(x-2)(x+2)
0=x-2   0=x+2
2=x      x=-2

Lucky Charms are sold in boxes with an advertised mean weight of 20.5 oz. The standard deviation is known to be 2.25 oz. A consu
Alinara [238K]

Answer:

Set of hypothesis.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ =  20.5 oz

Sample mean, \bar{x} = 20.4 oz

Sample size, n = 50

Population standard deviation, σ =  2.25 oz

First, we design the null and the alternate hypothesis

H_{0}: \mu = 20.5\text{ oz}\\H_A: \mu < 20.5\text{ oz}

We use One-tailed z test(left tailed) to perform this hypothesis.

Formula:

z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }

Putting all the values, we have

z_{stat} = \displaystyle\frac{20.4 - 20.5}{\frac{2.25}{\sqrt{50}} } = -0.3142

Based on the significance level, we can make our decision and complete the hypothesis testing.

We may accept the null hypothesis or fail to accept depending on different significance level.
