Answer:
Step-by-step explanation:
<u><em>x-intercept</em></u>
<u><em>y-intercept </em></u>
1) Call x the sample mean = 3.56
2) Call s the sample standard deviation = 0.2
3) Given that the variable is normally distributed and the sample is large, you determine the interval of confidence from:
x +/- Z(0.5) s/√n
Wehre Z(0.5) is the value of the probabilities over 5% (90% of confidence mean to subtract 10%, which is 5% for each side (tails) of the normal distribuition) and is taken from tables.
Z(0.5) = 0.3085
Then the inteval is
x +/- 0.385 *s /√n = 3.56 +/- 0.385 * 0.2/√45
3.56 +/- 0.011 = ( 3.549, 3.571). This is the answer.
Answer:
It's 6/7
Step-by-step explanation:
5 is 120
and 6 is 650
and rounded idk what it is
but hope it helps
Answer:
6 +4 (11-2)
6 + 4 (9)
6+ 36
42
42÷3²
42÷9
4.6666667
Step-by-step explanation:
i hope the divided by 3^2 was the next step and not a part of the equation because if it was a part of the original equation than the answer is wrong
