Enter your answer by filling in the blanks ( ____ , ____ ). Round final answers to 2 decimal places.

Answer #1

Refer t-table or use excel function
"* =T.INV.2T(0.19,28)*" to find the value of
t.

Use the t-distribution to find a confidence interval
for a mean μ given the relevant sample results. Give the best point
estimate for μ, the margin of error, and the confidence interval.
Assume the results come from a random sample from a population that
is approximately normally distributed.
A 90% confidence interval for μ using the sample results x¯=3.5,
s=0.4, and n=100

Use the normal distribution to find a confidence interval for a
difference in proportions p1-p2 given the relevant sample results.
Assume the results come from random samples.
A 90% confidence interval for p1-p2 given thatp^1=0.25 with
n1=40 and p^2=0.35 with n2=120
Give the best estimate for p1-p2, the margin of error, and the
confidence interval.
Round your answer for the best estimate to two decimal places and
round your answers for the margin of error and the confidence
interval to...

Find the critical values for a 95% confidence interval using the
chi-square distribution with 15 degrees of freedom. Round the
answers to three decimal places.

Use the normal distribution to find a confidence
interval for a difference in proportions
p1-p2
given the relevant sample results. Assume the results
come from random samples.

p1-p2
given that
p^1=0.76
with
n1=590
and
p^2=0.65
with
n2=340
Give the best estimate for
p1-p2
, the margin of error, and the confidence
interval.
Round your answer for the best estimate to two decimal
places and round your answers for the margin of error and the
confidence...

Use the t-distribution to find a confidence interval
for a difference in means μ1-μ2 given the relevant sample results.
Give the best estimate for μ1-μ2, the margin of error, and the
confidence interval. Assume the results come from random samples
from populations that are approximately normally distributed.
A 90% confidence interval for μ1-μ2 using the sample results
x¯1=81.1, s1=10.3, n1=35 and x¯2=67.1, s2=7.9, n2=20
