If n = 100 and mean = 219 and sample standard deviation =

35, which of the following Python lines outputs the 95%

confidence interval?

Question 3 options:

a)

import scipy.stats as st

n = 100

df = n - 1

mean = 219

stderror = 35.0/(n**0.5)

print(st.t.interval(0.90, df, mean, stderror))

b)

import scipy.stats as st

n = 100

df = n - 1

mean = 219

stderror = 35.0/(n**0.5)

print(st.t.interval(0.95, df, mean, stderror))

c)

import scipy.stats as st

n = 100

df = n - 1

mean = 219

stderror = 0.5/(n**35)

print(st.t.interval(0.95, df, mean, stderror))

d)

import scipy.stats as st

n = 219

df = n - 1

mean = 100

stderror = 35.0/(n**0.5)

print(st.t.interval(0.95, df, mean, stderror))
