What is the equation represented by the order pairs {(0,32),(1,16),(2,8),(3,4)}?

bagirrra123 [75]

Answer:

The equation represented by the ordered pair is;

y = 2^(5-x)

Step-by-step explanation:

Here, we want to write the equation represented by the ordered pairs

From what we have in the question, we can see that while the x-values increase in arithmetic progression of 1

The y-values decrease in order of two geometrically

Thus, the equation is;

y = 2^(5-x)

In 1960, census results indicated that the age at which men in a certain region first married had a mean of 23.5 years. We want

alina1380 [7]

Answer:

There is not sufficient evidence that the mean age of first marriage differs the mean age in 1960.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 23.5 years

Sample mean, $\bar{x}$ = 24.3 years

Sample size, n = 40

Alpha, α = 0.10

Sample standard deviation, s = 5.3 years

P-value = 0.346

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 23.5\text{ years}\\H_A: \mu \neq 23.5\text{ years}$

We use Two-tailed t test to perform this hypothesis.

Formula:

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

Putting all the values, we have

$t_{stat} = \displaystyle\frac{24.3 - 23.5}{\frac{5.3}{\sqrt{40}} } = 0.9546$

P-value = 0.346

Since the calculated p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.

Conclusion:

Thus, there is not sufficient evidence that the mean age of first marriage differs the mean age in 1960.
