Imagine we conduct a one-way independent ANOVA with four levels on our independent variable and obtain a significant result. Giv

en that we had equal sample sizes, we did not make any predictions about which groups would differ before the experiment and we want guaranteed control over the Type I error rate, which would be the best test to investigate which groups differ?

Answer:

(C) Bonferroni

Explanation:

A Bonferroni test is a type of multiple comparison test used in statistical analysis. It is used when several dependent or independent statistical tests are being performed simultaneously.Bonferroni designed a test or an adjustment to prevent data from incorrectly appearing to be statistically significant.

It is used to counteract the problem of multiple Comparisons.

The Bonferroni correction is appropriate when a single false positive in a set of tests would be a problem. It is mainly useful when there are a fairly small number of multiple comparisons and you're looking for one or two that might be significant.

Answer:

The answer to your question is below

Step-by-step explanation:

5)                                2x² -7x + 34

                       x + 5   2x³ + 3x² - x + 1

                                 -2x³ -10x²

                                   0   - 7x² - x

                                        +7x² +35x

                                           0   +34x + 1

                                                 -34x - 170

                                                    0   - 160

Quotient = 2x² - 7x + 34

Remainder = -160

6)                                       2x² - 3x  + 1

                             3x + 1   6x³ - 7x² + 0x + 2

                                         -6x³ -2x²

                                          0    -9x² + 0x

                                                +9x² +3x

                                                   0   +3x + 2

                                                        - 3x - 1

                                                           0  + 1

Quotient = 2x² - 3x + 1

Remainder = 1

The area of the conference table in Mr. Nathan’s office must be no more than 175 ft2. If the length of the table is 18 ft more t
valentina_108 [34]
The answer is  0 < x <span>≤ 7 
</span>
First, we know that width =  x
Which means that length = x +18

So, the possible equation for the Table's area is

X (X + 18)  ≤ 175

X^2 + 18x - 175  <span>≤ </span>0

Next, we need to calculate is by using complete square method
x^2 + 18x + 81 <span>≤ 175 + 81

(x + 9)^2 </span><span>≤ 256

|x + 9| </span><span>≤ sqrt(256)

|x + 9| </span><span>≤ +-16

-16 </span>≤ x + 9 <span>≤ 16

</span>-16 - 9 ≤ x <span>≤ 16 - 9

</span>-25 ≤ x <span>≤ 7

Since the width couldn't be negative, we can change -25 with 0,

so it become
</span> 0 < x ≤ 7
