Null:

Alternative:

Answer #1

**Solution:**

Claim: new energy drink that significantly increase your energy during workouts, as compared to people who drink only water during workouts.

We have to state null and alternative hypothesis.

**Null:** There is no significant increase in mean
energy during workouts of people who drink new energy drink as
compared to people who drink only water during workouts.

in symbolic form:

where

= mean energy during workouts of people who drink new energy drink

= mean energy during workouts of people who drink water only.

**Alternative:** There is significant increase in
mean energy during workouts of people who drink new energy drink as
compared to people who drink only water during workouts.

A researcher at UniSA’s School of Health Sciences believes that
energy drink consumption may increase heart rate. She believes that
heart rate in beats per minute (bpm) is normally distributed with
an average of 70 bpm for adults. To test her belief, she takes a
random sample of 25 adults who regularly consume energy drink.
Their heart rates are 65, 64, 75, 79, 60, 84, 63, 91, 81, 98, 92,
69, 78, 85, 88, 87, 70, 80, 73, 74, 83,...

The label on a companies energy drink claims that they contain
250 mg/oz. The mean caffeine concentration of 15 randomly sampled
drinks was 267, with a standard deviation of 12.1. Was a two-tailed
test used to assess the alternative hypothesis? What is the
P-value?

A soft drinks distributor claims that a new advertising display
will increase sales by average of 50 cases per week.For a random
sample of 25 stores, the average sales increase was 41.3 cases and
the sample standard deviation was 12.2 cases. Test at the 5% level
the null hypothesis that population mean sales increase is at least
50 cases.
A. The test statistic is -1.645; The critical value is -3.57;
we reject Ho and accept the alternative.
B. The test...

In an advertisement, a pizza shop claims its mean delivery time
is 30 minutes. A consumer group believes that the mean delivery
time is greater than the pizza shop claims. A random sample of 41
delivery times has a mean of 31.5 minutes with standard deviation
of 3.5 minutes. Does this indicate at a 5% significance level that
the mean delivery time is longer than what the pizza shop
claims?
Step 1: State the null and alternative hypothesis.
Step 2:...

The manufacturer of a new antidepressant claims that,
among all people with depression who use the drug, the proportion p
of people who find relief from depression is at least 80%. A random
sample of 205 patients who use this new drug is selected, and 160
of them find relief from depression. Based on these data, can we
reject the manufacturer's claim at the 0.05 level of significance?
Perform a one-tailed test. Then fill in the table below. Carry your...

Survey 40 people and ask them this question: “What is your
favorite soft drink?” You record your results and realize that 10
of those people chose Dr. Pepper. You calculated your sample
proportion for the 10 individuals who chose Dr. Pepper, and
standard error. The following are your results:
Proportion: 0.25
Standard Error: 0.0684
You then ask a friend what percentage of people do you think
would say that Dr. Pepper is their favorite soft drink? You friend
claims that...

McBeans magazine recently published a news article about
caffeine consumption in universities that claims that 80% of people
at universities drink coffee regularly. Moonbucks, a popular coffee
chain, is interested in opening a new store on UBC campus. After
reading McBeans' article, they will consider opening a store in UBC
if more than 80% of the people in UBC drink coffee regularly. A
random sample of people from UBC was taken, and it was found that
680 out of 810...

1)You are conducting a study to see if the average female life
expectancy is significantly more than 93. If your null and
alternative hypothesis are:
H 0 : μ ≤ 93
H 1 : μ > 93
Then the test is:
two tailed
right tailed
left tailed
2)
If your null and alternative hypothesis are:
H0:μ=40H0:μ=40
H1:μ>40H1:μ>40
Then the test is:
right tailed
two tailed
left tailed
3)
Below is a hypothesis test set up by a student who recently...

A USA Today article claims that the proportion of people who
believe global warming is a serious issue is 0.78, but given the
number of people you've talked to about this same issue, you
believe it is different from 0.78. The hypotheses for this test are
Null Hypothesis: p = 0.78, Alternative Hypothesis: p ≠ 0.78. If you
randomly sample 23 people and 15 of them believe that global
warming is a serious issue, what is your test statistic and...

Hypothesis Test Example For Proportions:
What proportion of people do not drink alcohol? You believe that
the proportion of people in the U.S.A. who do not drink is less
than 15%. To determine if you are correct, you take a SRS of 400
U.S. residents, and find the proportion of people who do not drink
in your sample is 0.22. Conduct a hypothesis test at the 5%
significance level.
A). Write the hypotheses for the test.
B). Check the assumptions...
