Answer:
x=55
Step-by-step explanation:
The 3 angles of a triangle add up to 180 degrees
<A + < B + <C = 180
x + 75+ 50 = 180
x + 125 = 180
subtract 125 from each side
x = 180-125
x = 55
Both methods assume a normal distribution of the data, but the z-tests are most useful when the standard deviation is known.
OR u can use , z-tests are used when we have large sample sizes (n > 30), whereas t-tests are most helpful with a smaller sample size (n < 30). Both methods assume a normal distribution of the data, but the z-tests are most useful when the standard deviation is known.
