Pat ran an experiment to test optimum power and time settings for microwave popcorn. His goal was to deliver
popcorn with fewer than 10% of the kernels left unpopped, on average. He determined that power 9 at 4 minutes was
the best combination. To be sure that the method was successful, he popped 8 more bags of popcorn (selected
at random) at this setting. All were of high quality, with the percentages of unpopped kernels shown below.
12.3, 10.8, 11.7, 11.1, 9.6, 7.2, 3.4, 2.7
Does this provide evidence that he met his goal of an average of fewer than 10% unpopped kernels? Use 0.05 as
the P-value cutoff level.
Choose the correct null and alternative hypotheses.
A. Ho: μ> 10
HA: μ = 10
t=
C. Ho: μ = 10
HA:μ> 10
E. Ho: μ< 10
HA: μ = 10
Calculate the test statistic.
(Round to three decimal places as needed.)
...
OB. Ho: μ# 10
HA: H = 10
D. Ho: μ = 10
HA: μ < 10
OF. Ho: μ = 10
HA: μ10
