Question

Directions: State the null and alternative hypothesis for each question in words and using symbols. Identify the response variable and explanatory variable and whether it is a experimental or observational study.

1) Is there a difference in commute times for male and females working San Francisco residents?

H0:

HA:

a) In words Ha:

i) Response variable=

ii) Explanatory variable=

iii) Observational or Experimental=

Answer #1

1)

H0 : i.e there is no difference in commute times for male and females working San Francisco residents

H1 : i.e there is significant difference in commute times for male and females working San Francisco residents

(i) Response Variable = **Commute Time**

(ii) Explanatory variable = **Gender**

(iii) Observational study : Here we are basically studying/observing the time taken for commuting for males and females in San Francisco area.

We can setup null and alternative hypotheses for decision
making. Remember in hypothesis testing the "equals" part will be
with the null hypothesis, so you can have less than or equal to,
greater than or equal to, or just equal to when defining the null
hypothesis. The alternative hypothesis will be, then, either
greater than, less than, or not equal to in relation to the above
null criteria. See below for how it looks symbolically for the
three possible setups....

Share with your peers the null and alternative hypotheses for a
decision that is relevant to your personal or professional life
(any example is fine). Remember in hypothesis testing the "equals"
part corresponds to the null hypothesis, so you can have less than
or equal to, greater than or equal to, or just equal to when
defining the null hypothesis. The alternative hypothesis will then
be either greater than, less than, or not equal to in relation to
the above...

Test the given claim. Identify the null hypothesis,
alternative hypothesis, test statistic, P-value, and then state
the conclusion about the null hypothesis, as well as the final
conclusion that addresses the original claim. Among 2199 passenger
cars in a particular region, 255 had only rear license plates.
Among 354 commercial trucks, 49 had only rear license plates. A
reasonable hypothesis is that commercial trucks owners violate laws
requiring front license plates at a higher rate than owners of
passenger cars....

alternative hypothesis in words and then symbols for each pf the
following situations.

sample of a 25 New Yorkers were asked how much sleep they get per
night. Do these data provide convincing evidence that New Yorkers
on average sleep less than 8 hours a night?

1. State the null hypothesis and the alternative hypothesis for
each of the following examples.
After low scores on the first exam, a chemistry teacher wants to
boost her students’ long-term retention of the material so she
introduces them to a new study technique to see if it improves
their memory for the material. She wants to see whether her class’
Exam 2 scores are significantly higher than their Exam 1
scores.

a. State the Null and Alternative
Hypotheses in words.
b. Perform the appropriate hypothesis
test using an Alpha of .05. Be sure to write what critical value
you are using in your work.
c. State your results first by saying
whether you reject or fail to reject the null hypothesis. Then
state the conclusion in your own words.
d. type in your hypotheses, the df
value you use, and the critical value. Also include your conclusion
and When you calculate...

19. For each of the following
claims
i) State the Null Hypothesis H0 and
the Alternate Hypothesis HA
ii) Indicate which is the claim.
iii) Determine whether the reject
region is left-tailed, right-tailed or two-tailed.
a) A consumer magazine reports that
the mean life of a dot-matrix printer is at least 3.5 years.
b) A realtor claims that rent for
studio apartments in new buildings in Brooklyn cannot be $1500 a
month.
c) A car dealer announces that the
mean...

For the following question, you need to check the requirements
and identify the null hypothesis, alternative hypothesis, test
statistic, P-value, critical values, then state the conclusion
about the null hypothesis, as well as the final conclusion that
addresses the original claim. Assuming the sample is independent
simple random sample. Use both the P-value method and critical
value method.

hypothesis for each of the following cases:

Identify the correct null hypothesis:

50%? In a sample of 200 babies, 96 were male. Test the
claim using a 1% significance level.
