Any geometric sequence can be expressed as:
a(n)=ar^(n-1), in this case a=64 and r=1/2 so
a(n)=64(1/2)^(n-1)
So the 2nd, 3rd, and 4th terms are:
32, 16, and 8
Answer:
Standard Error is increased.
Step-by-step explanation:
Type 2 error is failure to reject a false null hypothesis. This is a 'false negative' result of hypothesis testing, represented by beta 'β'.
Power of test is 1 - β, which shows probability of accurately stating a null hypothesis false, when it is actually false.
Increased sample size increases the power of test accuracy, hence reduces type 2 error. Increased level of significance implies higher probability of rejecting a true null hypothesis, ie type 1 (false positive) error. So, it decreases type 2 error.
Standard Error increase implies lower level of t statistic , ie = (x - u) / (s / √ n) Lower the t value, higher is the probability of not rejecting null hypothesis, which implies higher chance of type 2 error.
Answer:
select A,C,E, and F
Step-by-step explanation:
Since -(9/16) is a negative number, it has no real square root. The square root of a negative number is usually represented by an imaginary number. Therefore, the answer to the question is OPTION D (No Real Root)
The answer is 13 because 74-9= 65. 65/5 = 13
