Erin scored 1 of 2, or in fraction form: 1/2
Lauren scored 6 of 8, or in fraction form: 6/8
Find common denominators. multiply 4 to numerator and denominator of 1/2
(1/2) x (4/4) = 4/8
4/8 > 6/8
Lauren was more successful
hope this helps
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.
X^2 = 16
x = 4
x = -4
good luck :)
