Answer:
(n + 2)² + 6
Step-by-step explanation:
pattern 1:
Total squares = 15
3² + 6 = 16
Pattern 2:
Total squares = 22
4² + 6
Pattern 3:
Total squares = 31
5² + 6
Looking at the series,
There is an Increment of 1 in squared integer as the pattern increases; there is also a constant integer of 6
Hence, expressing the nth pattern in the form ;
(n + a)² + b
Where n is the nth pattern ; a = (Coefficient of n² in first pattern - 1) = (3 - 1) =2 ;
b = 6
Hence, we have ;
(n + 2)² + 6
Answer: [a] 95% confidence interval = 4.4 < Ẍ <9.2
[b] margin of error = ± 2.4
Step-by-step explanation:
here let us carefully look into this problem,
from the question, we have that Ẍ = 6.8, and SE = 1.2
let us begin
(a). asked to calculate the 95% confidence interval we have;
95% C.I = Ẍ ± 2 (SE) = 6.8 ± 2(1.2) = 6.8 ± 2.4
95% C.I = (4.4, 9.2)
this gives the confidence interval to be (4.4 < Ẍ < 9.2).
(b). the error margin is ± 2.4, which implies that our estimate of 6.8 pounds is within 2.4 pounds of the true mean weight gain for the population.
cheers i hope this helped a great deal !!1
