You are constructing a 95% confidence interval of a sample space consisting of n = 40 values and a
population standard deviation of 2.6. the population appears to be skewed. determine whether a
margin of error should be calculated using a critical value of za/2, a critical value of ta/2, or neither.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
