If earning more money from a college degree occurs, a researcher is interested in finding out. She is aware that the average annual household income in thousands is μ<=80.
The null hypothesis is a claim made about the population parameter in relation to the test's goal and in opposition to the alternative hypothesis.
- The term "null hypothesis" refers to a researcher's attempt to reject or "nullify" a commonly held assumption (such as that the sky is blue). A null hypothesis is "a statistical theory suggesting that no statistical relationship exists between given observed variables," according to a more formal definition.
- It always contains = , ≤ , ≥ signs.
- The results will be examined using a one-tailed hypothesis test.
Hence, μ<=80

Answer:
5, 7, 11, 19, 35
Step-by-step explanation:
Using the recursive formula and a₁ = 5 , then
a₂ = 2a₁ - 3 = (2 × 5) - 3 = 10 - 3 = 7
a₃ = 2a₂ - 3 = (2 × 7) - 3 = 14 - 3 = 11
a₄ = 2a₃ - 3 = (2 × 11) - 3 = 22 - 3 = 19
a₅ = 2a₄ - 3 = (2 × 19) - 3 = 38 - 3 = 35
Thus the first 5 terms are
5, 7, 11, 19, 35
Answer:
Step-by-step explanation:
3 - 13x - 7x^2 - (5x^2 + 12x - 10) =
3 - 13x - 7x^2 - 5x^2 - 12x + 10 =
- 12x^2 - 25x + 13 <===
Answer:
surface area: 7241.25
Step-by-step explanation:
using this formula for surface area of cyclinder: 2πrh+2π
diameter = 2r --> 39.2 = 2r
so r= 19.6
