Answer:
3 83/100
Step-by-step explanation:
The part 83/100 can not be simplified more because 83/100 is in its simplest form already.
Answer:
P (x≥ 57) = 6.7789 e^-8
Step-by-step explanation:
Here n= 100
p = 31/100 = 0.31
We formulate the null hypothesis that H0: p= 0.31 against the claim Ha: p≠0.31
The significance level is chosen to be ∝= 0.05
The test statistic x to be used is X, the number U.S. residents is to be taken which is at least 57
The binomial calculator gives the
P (x≥ 57) = 6.7789 e^-8
IF ∝= 0.05 then ∝/2 = 0.025
We observe that P (x≥ 57) is less than 0.025
Hence we reject H0 and conclude that p ≠0.31
This is true because for normal distribution the median = mean which is usually the 50 % of the data.
