Answer:
(80.4942, 94.9052)
Step-by-step explanation:
The sample mean is x = 87.7.
The sample standard deviation is s = 11.26.
At 99% confidence and 19 degrees of freedom, the critical value is t = 2.861.
The confidence interval is:
x ± t (s/√n)
87.7 ± 2.861 (11.26 / √20)
87.7 ± 7.2053
(80.4947, 94.9053)
Answer:
Good Luck!
Step-by-step explanation:
Base on the triangle below or in your problem, to calculate the x in the triangle having one angle measure 53 degree and the side measures 35 and the value of x is equals to 112.79. I hope you are satisfied with my answer and feel free to ask for more if you clarifications and further questions
