Answer:
153.158 ; 177.642
Step-by-step explanation:
Given the following:
Sample mean (m) = 165.40
Sample standard deviation (s) = 21.70
Sample size (n) = 17
α = 98%
Confidence interval = m ± z(SE)
z at 98% = 2.326
SE = s/√n
SE = 21.70/√17 = 5.2630230
Hence,
Confidence interval = 165.40 ± 2.326(5.2630230)
165.40 - 12.241791498 OR 165.40 + 12.241791498
153.158 ; 177.642
Answer:
u = 119
Step-by-step explanation:
The sum of the angles of a triangle add to 180
31+ u-40 + u-49 = 180
Combine like terms
2u -58 = 180
Add 58 to each side
2u-58+58 = 180+58
2u =238
Divide each side by 2
2u/2 = 238/2
u =119
