Mathematics
1 answer:
polet [3.4K]4 years ago
8 0

Answer:

x² + 1

or if we suppose

x² + 1 = 0 the n we get value of x

x = ±1

Step-by-step explanation:

x²+x/x​    (cancel out both x/x we get)

x² + 1

Let suppose

x²+x/x​ = 0

x² + 1 =0

x²=-1

taking square root on both side we get

x = ±1

valkas [14]

Answer:

Since p-value > ∝, H0 is accepted

Step-by-step explanation:

Calculating gives the following results.

<u>ANOVA Table</u>

<u>Source DF               Sum             Mean      F Statistic P-value</u>

                               <u>  of Square           Square</u>

Groups     6         191.61                      31.935        0.020          0.999

(b/w groups)

Error

(within 14          21736.08                1552.577

<u> groups)                                                                                                     </u>

<u>Total  20          21927.69 1096.385                                          </u>

1. H0 hypothesis

Since p-value > ∝, H0 is accepted.

Hence the averages of all groups considered to be equal.

Or the difference between the averages of all groups is not big enough to reject H0.

2. P-value

P-value equals 0.999. This means that if we would reject H0, the chance of type1 error (rejecting a correct H0) would be too high i.e  (99.99%)

The bigger  p-value  supports H0.

3. The statistics

The test statistic F equals 0.020, which lies in the accepted range: [-∞ : 2.8477]
