Step-by-step explanation:
A polynomial in standard form begins with the term with the largest exponent and the remaining terms in descending order of exponents.
given
15 - 6x + 13x² - 1 ←
is largest exponent, hence
15 + 13x² - 6x - 1 ← in standard form
Answer:
Step-by-step explanation:
Given that :
population Mean = 15000
standard deviation= 1200
sample size n = 100
sample mean = 16000
The null and the alternative hypothesis can be computed as follows:
Using the standard normal z statistics
z = 8.333
degree of freedom = n - 1 = 100 - 1 = 99
level of significance ∝ = 0.05
P - value from the z score = 0.00003
Decision Rule: since the p value is lesser than the level of significance, we reject the null hypothesis
Conclusion: There is sufficient evidence that the Dean claim for his graduate students earn more than average salary of $15,000
