Asample of 20 international students attending an urban u. s. university found that the average amount budgeted for expenses per month was $1,612.50 with a standard deviation of $1,179.64. find a 95% confidence interval for the mean monthly expense budget of the population of international students.

step-by-step explanation:

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.

hit or miss i guess they never miss huh
