Answer:
Option c. The result is significant at the 0.020.02 level.
Step-by-step explanation:
We are given the following in the question:
We are conducting a one tailed hypothesis test with alternate hypothesis
The z test calculated for the same is
z=2.3
We calculate the p-value from the standard normal table.
p value = 0.010724 at 0.05 significance level.
The result is significant
p value = 0.010724 at 0.01 significance level.
The result is not significant
p value = 0.010724 at 0.02 significance level.
The result is significant at 0.02 significance level.
Thus, the correct answer is
Option c. The result is significant at the 0.020.02 level.
Answer:
(See explanation for further details)
Step-by-step explanation:
a) Let consider the polynomial . The polynomial is in standards when has the form
, where
is the order of the polynomial. The example has the following information:
,
,
,
,
.
b) The closure property means that polynomials must be closed with respect to addition and multiplication, which is demonstrated hereafter:
Closure with respect to addition:
Let consider polynomials and
such that:
and
, where
Hence, polynomials are closed with respect to addition.
Closure with respect to multiplication:
Let be a polynomial such that:
And an scalar. If the polynomial is multiplied by the scalar number, then:
Lastly, the following expression is constructed by distributive property:
Hence, polynomials are closed with respect to multiplication.
