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.
I hope this helps you
p^2+13p-30=0
p +15
p -2
(p+15)(p-2)=0
p= -15
p=2
Answer:
The answer is "0.9461"
Step-by-step explanation:
Given:
≈
The value is in between 0 and 1 then:
The above-given series is an alternative series, and it will give an error, when the nth term is bounded by its absolute value, that can be described as follows:
So,
≈
