a researcher wants to find out how much a person watches television causes a person to like bourbon whisky more. to do this she asks each participant if they watch tv more or less than 2 hours per day and then has them take a likert scale of how much they like bourbon whisky. which test statistic would you use?
chi-square test statistic is statistically significant.
What is Test Statistic?
A statistic employed in statistical hypothesis testing is known as a test statistic. A test statistic, which can be thought of as a numerical summary of a data set that condenses the data into a single value that can be used to conduct the hypothesis test, is how a hypothesis test is commonly expressed.
To determine whether the amount of television a person watches is related to their liking for bourbon whisky, the researcher could use a chi-square test of independence.
The chi-square test is a statistical test that is used to determine whether there is a significant association between two categorical variables.
In this case, the two variables of interest are television watching (more or less than 2 hours per day) and liking for bourbon whisky (measured using a Likert scale).
The chi-square test statistic is calculated based on the observed frequencies of each combination of television watching and liking for bourbon whisky, and it is used to determine whether the observed frequencies are significantly different from the frequencies that would be expected if the two variables were independent.
If the chi-square test statistic is statistically significant, it indicates that there is a significant association between the two variables, and the researcher can conclude that television watching is related to liking for bourbon whisky.
Hence, chi-square test statistic is statistically significant.

Order from least to greatest. .46 4/6 .046 1/10 -4
(/ means fraction)
Answer:
-4, 0.046, 1/10, 0.46, 4/6
Step-by-step explanation:
First, we know that -4 is the least because it is a negative number.
Next, we need to convert the fractions to decimals. 1/10 is 0.1, and 4/6 is 0.66.
Then, we order the decimals.
0.046 is the next smallest, because it is a hundredth, and the remaining decimals are tenths and therefore greater.
We compare the remaining decimals, which are 0.10, 0.46, and 0.66. These are easy to compare and order.
Now, we've compared and ordered all the numbers. We can convert the fractions back into their original form.

Ways to find the perpendicular line of a linear equation are by solving for y, convert the equation of the given line into slope-intercept form.
Describe perpendicular.A straight line that forms a 90° angle with another line is said to be perpendicular. A small square is placed between two perpendicular lines, as seen in the illustration, to indicate a right angle, also known as a 90° angle. The two lines in this instance are considered to be perpendicular to one another because they intersect at a straight angle.

what is the slope between (-2,-19) and (-12,11)
Answer:
m = -3
Step-by-step explanation:
The slope is rise/run or (y2 - y1) / (x2 - x1)
We see the y increase by 30 and the x decrease by 10, so the slope is
-30/10 = -3
So, m = -3
Answer:
Slope = -3
Step-by-step explanation:
Formula of slope,
→ Slope(m) = (y2 - y1)/(x2 - x1)
Now the slope will be,
→ m = (y2 - y1)/(x2 - x1)
→ m = (11 -(-19))/(-12 -(-2))
→ m = (11 + 19)/(-12 + 2)
→ m = 30/-10
→ m = -(30/10)
→ [ m = -3 ]
Hence, the slope is -3.

The figure's circumference, as seen in the diagram, is 60.84 m.
What are some instances of perimeters?
The perimeter of an object is the space surrounding it. For instance, your house has a fenced-in yard. The perimeter is the length of the fence. If the yard is 50 feet by 50 feet, your fence is 200 feet long.
The formula below is used to determine the figure's perimeter.
Formula:
Equation 1: P = 2L + W + W / Equation 1:
P = The figure's perimeter
L is the figure's length.
W is the figure's width.
Considering the query,
Given:
L = 15 m\sW = 12 m\sπ = 3.14
Replace the values in equation 1 with these ones.
P = (15×2)+12+(12×3.14/2)
P = 30+12+18.84
P = 60.84 m
As a result, the figure's perimeter is 60.84 meters.

A number's square root is a value that, when multiplied by itself, yields the original number. The other way to square an integer is to find its square root. Squares and square roots are hence related concepts.
Assuming that x is the square root of y, the equation would be written as x=y or as x2 = y. The radical symbol for the number's root is "" in this instance. The square of the positive number is represented by multiplying it by itself. The original number is obtained by taking the square root of the square of a positive number.
As per the question, 3 √ 4 √ x when x =4096
first we need to calculate square root of 4096 by prime factorisation method
4096 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2
4096 = (2 × 2) × (2 × 2) × (2 × 2) × (2 × 2) × (2 × 2) × (2 × 2)
√4096 = √((2 × 2) × (2 × 2) × (2 × 2) × (2 × 2) × (2 × 2) × (2 × 2))
√4096 = 2 × 2 × 2 × 2 × 2 × 2
√4096 = 64
Therefore the square root of 4096 = 64.
x=64
now putting the value of x in 3 √ 4 √ x
= 3 √ 4 √ 64
= 3 √ 256
=3×16
