Week 7 Assignment: Conducting a Hypothesis
Test for Mean - Population Standard Deviation
Known: P-Value Approach
1. What is the p-value of a two-tailed one-mean hypothesis test, with a test statistic
of z0=−1.73? (Do not round your answer; compute your answer using a value from
the table below.)
61 meters. During a practice
2. Mary, a javelin thrower, claims that her average throw is
session, Mary has a sample throw mean of 55.5 meters based on 12 throws. At the
1% significance level, does the data provide sufficient evidence to conclude that Mary's
mean throw is less than 61 meters? Accept or reject the hypothesis given the sample
data below.
H0:μ=61 meters; Ha:μ<61 meters
α=0.01 (significance level)
z0=−1.99
p=0.0233
The Right Choice Is Option E
i.e
Do Not Reject The Null Hypothesis because The P value is
0.02333 is Greater than The Significance Level 0.01
3. What is the p-value of a two-tailed one-mean hypothesis test, with a test statistic
of z0=0.27? (Do not round your answer; compute your answer using a value from the
table below.)
