Considering that we have the standard deviation for the sample, the t-distribution will be used, and the critical value is t = 2.6682.
<h3>When should the t-distribution and the z-distribution be used?</h3>
- If we have the standard deviation for the sample, the t-distribution should be used.
- If we have the standard deviation for the population, the z-distribution should be used.
In this problem, σ is not known, hence we get the standard deviation of the sample from the histogram and the t-distribution is used.
Using a t-distribution calculator, considering a <em>confidence level of 99%</em> and 56 - 1 = <em>55 df</em>, the critical value is t = 2.6682.

2 blue, 4 green, 3 white....total of 9 chips
P(blue) = 2/9
replacing
P(green) = 4/9
P(both events happening) = 2/9 * 4/9 = 8/81 <==
0.065 meters is equal to 65 millimeters
The line has a slope of -6 and a y intercept of 7.
The linear equation is given by:
y = mx + b;
where m is the slope of the line, b is the y intercept, y, x are variables.
The equation of the line passing through the points (6.-29) and (-4,31) is:
Hence the line has a slope of -6 and a y intercept of 7.

Answer:
the answer should be always, which would be b
Step-by-step explanation:
if you have a reciprocal 3/2 then the fraction would be 2/3 which is proper. you just flip the numbers.
