Answer:
Interval [16.34 , 21.43]
Step-by-step explanation:
First step. <u>Calculate the mean</u>

Second step. <u>Calculate the standard deviation</u>



As the number of data is less than 30, we must use the t-table to find the interval of confidence.
We have 6 observations, our level of confidence DF is then 6-1=5 and we want our area A to be 80% (0.08).
We must then choose t = 1.476 (see attachment)
Now, we use the formula that gives us the end points of the required interval

where n is the number of observations.
The extremes of the interval are then, rounded to the nearest hundreth, 16.34 and 21.43

Answer:
dddddddddddddddddddddddd could be rewritten as d^24 because d*d*d*d*d*d*d... = d^24
Step-by-step explanation:
When we multiply all of the d's together we get
.
It’s b I’m positive because I did 1.25 to the power of 3 and put that into fractional form
