The number is 8 since 9 squared is 81
T1 = 3
t2 = 2*t1 = 6
t3 = 2*t2 = 12
t4 = 24
t5 = 48
Answer:
Interval is given with 97% confidence. Thus there is 3% probability that interval is not true.
Step-by-step explanation:
In Statistics, estimated intervals are given with some confidence level. In this example person develop the interval with 97% confidence.
<em>Statistically</em>, this means that the person can be 97% sure (not 100%) that population mean is 74.3 < µ < 78.3. There is still 3% probability that population mean falls outside of the interval.
Small sample size may also lead wrong estimates.
Answer: B: The person counts 24 horses and 50 humans.
