6. A hypothesis test in which rejection of the null hypothesis occurs for values of the point estimator in either tail of the sa
natita [175]

Answer:

A two-tailed test.

Step-by-step explanation:

ANOVA is a short term or an acronym for analysis of variance which was developed by the notable statistician Ronald Fisher. The analysis of variance (ANOVA) is typically a collection of statistical models with their respective estimation procedures used for the analysis of the difference between the group of means found in a sample. Simply stated, ANOVA helps to ensure we have a balanced data by splitting the observed variability of a data set into random and systematic factors.

In Statistics, the random factors doesn't have any significant impact on the data set but the systematic factors does have an influence.

Basically, the analysis of variance (ANOVA) procedure is typically used as a statistical tool to determine whether or not the mean of two or more populations are equal through the use of null hypothesis or a F-test.

Hence, the null hypothesis for an analysis of variance (ANOVA) requires that all treatments or samples should be generated from populations having the same mean.

A hypothesis test in which rejection of the null hypothesis occurs for values of the point estimator in either tail of the sampling distribution is called a two-tailed test.

a cylinder shaped glass with a base area of 7.07 square inches and a height of 6 inches weighs 1.06 ounces when empty. the glass
inn [45]
We know, volume of Cylinder = πr²h
Now, base area = πr² = 3.14 * r² = 7.07
r = √2.25
r = 1.50

Now, volume of water = 3.14 * (1.50)² * 5
v = 3.14 * 2.25 * 5
v = 35.325 in³

Weight of 1 in³ = 0.6 Ounce
so, 35.325 in³ = 0.6 * 35.325 = 21.195 Ounce
Total Weight = Glass weight + water weight
w = 1.06 + 21.195
w = 22.255 Ounce

In short, Your Answer would be 22.255 Ounces

Hope this helps!

Bitsy Betsy is only 4 and half feet tall. How many inches is she?
max2010maxim [7]

Answer:

54 inches

Step-by-step explanation:

first you're going to want to put four and a half feet into a decimal (4.5) and multiply it by how many inches are in 1 ft ( 12). after that you're going to want to count how many decimal paces there are (2) and move your decimal at the end of 5400 to 54.00. The extra 0s are not needed.

Help please!!<br> 1. What is the value of n?<br> 2.What is the value of n?
lana66690 [7]

Using the intersecting chord theorem:

15 x 2 = 5 x n

Simplify:

30 = 5n

Divide both sides by 5:

n = 30/5

n = 6 m



8 x n+8 = 16 x n+2

Simplify:

8n +64 = 16n +32

Subtract 8n from both sides:

64 = 8n +32

Subtract 32 from both sides:

32 = 8n

Divide both sides by 8:

n = 32 /8

n = 4

Paul predicts that n stalks of corn planted together will produce (2n2–2n)(2n2–2n) ears of corn. If Paul plants three corn plant
Free_Kalibri [48]
Given that the production of n stalks of corn planted has been modeled by (2n^2-2n), then the approximate ears of corn produced by 3 stalks will be given by:
2n^2-2n
plugging in n=3 in the formula we get:
2(3)^2-2(3)
simplifying we get:
2(9)-6
=18-6
=12
the answer is: 12 ears
