Step-by-step explanation:
The information provided is:

The test statistic is:


Thus, the value of the test statistic is <em>z</em> = 3.34.
Answer:
These are geometric or telescoping series.) A. ∞. ∑ k=3. 5. 2k . Answer: ... k=3. 5. 2k. = 5. 23. +. 5. 24. +. 5. 25. + ···. This is a geometric series with ratio r = 1/2. ... 516) with f(x)=1/(x ln(x)).
Answer:
not arithmetic
Step-by-step explanation:
An arithmetic sequence has a common difference d between consecutive terms.
Given
= 2n² - 1
Substitute in n = 1, 2, 3, 4 to generate the first 4 terms of the sequence
= 2(1)² - 1 = 2 - 1 = 1
= 2(2)² - 1 = 8 - 1 = 7
= 2(3)² - 1 = 18 - 1 = 17
= 2(4)² - 1 = 32 - 1 = 31
check the difference between consecutive terms
7 - 1 = 6
17 - 7 = 10
31 - 17 = 14
The differences are not common hence not an arithmetic sequence
