Ariadne is 5 feet tall because 18 is 6x3 which would mean you would have to divide 15 by three to get the answer which is 5.
Answer:
The critical value approach and the p-value approach gave the same result.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 4 hours
Sample mean,
= 4.5
Sample size, n = 460
Alpha, α = 0.051
Population standard deviation, σ = 1.00 hour
First, we design the null and the alternate hypothesis
We use One-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, low-income families are exposed to more than 4.0 hours of daily background television.
p value at z-stat 3.87 is 0.000054. Since p-value is less than the significance level. We reject the null hypothesis.
Hence, the critical value approach and the p-value approach gave the same result.
The length of the rectangle that makes the area to be 273 square feet is 21 feet.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent the length of the rectangle, hence:
Length * width = area
13 * x = 273
x = 21 feet
The length of the rectangle that makes the area to be 273 square feet is 21 feet.
