Answer:
6.5
Step-by-step explanation:
9 + 4 = 13 divide by 2 = 6.5 is your answer.
42%7=6. 6 times 5 is 30. 30 cakes in 5 days.
Males that watched action movies : 13
males that watched drama movies : 5
so there are (13 - 5) = 8 more that watched action then drama
X=1, y=3 because 2x1 is 2 and 3x3 is 9, 2 plus 9 equals 11 and 11 plus 4 equals 15
Step-by-step explanation:
Confidence interval = mean ± margin of error
CI = μ ± ME
The mean is μ = 8.7.
Margin of error = critical value × standard error
ME = CV × SE
At 95% confidence and 9 degrees of freedom, CV = 2.262.
SE = s / √n
SE = 3.3 / √10
SE = 1.04
The margin of error is:
ME = 2.262 × 1.04
ME = 2.36
CI = 8.7 ± 2.36
CI = (6.34, 11.06)
