Answer:
<h3>"When constructing a confidence interval for a population mean, if a population is normally distributed and a small sample is taken, then the distribution of is based on the <u> "t" </u>distribution</h3>
Step-by-step explanation:
Given that "When constructing a confidence interval for a population mean, if a population is normally distributed and a small sample is taken, then the distribution of is based on the "<u>t"</u>distribution."
Because the given sample size is smaller so we have to use the "t" distribution for constructing the confidence interval for a given population
Answer:
55.5
Step-by-step explanation:
find the median - in this case it's 60
then group the upper and lower halves of the data:
(11, 19, 35, 42) 60 (72, 80, 85, 88)
now we find the medians of those sets:
35 + 19/2 = 54/2 =27
80 + 85/2 = 165/2 = 82.5
then subtract those two medians to find the interquartile:
82.5 - 27 = 55.5
346
It is .346 times 1,000
Answer:
1.5 is the answer
Step-by-step explanation:
Answer:
(a)
Step-by-step explanation:
To determine if the points are a solution to the equation.
Substitute the coordinates of the point into the left side of the equation and if equal to the right side then they are a solution.
(2, 5)
- 3(2) + 4(5) = - 6 + 20 = 14 ← True
(4, 6)
- 3(4) + 4(6) = - 12 + 24 = 12 ← False
Thus (2, 5) is the only solution to the equation → (a)
