a.
To determine
Identify the three variables in Figure 2.86 as categorical or quantitative.
b.
To determine
Identify the two regions that seem to have the greatest happiness score.
Identify the two regions that seem to have the greatest ecological footprint.
c.
To determine
Identify the region that seems to have the lowest happiness score.
Check whether the ecological footprint tends to be high or low in that area.
d.
To determine
Identify whether there is a positive relationship between happiness score and ecological footprint by ignoring the region.
e.
To determine
Identify whether there is positive relationship between happiness score and ecological footprint by considering only region 2.
f.

A researcher wishes to estimate, with 90% confidence, the population proportion of adults who support labeling
legislation for genetically modified organisms (GMOs). Her estimate must be accurate within 4% of the true proportion.
(a) No preliminary estimate is available. Find the minimum sample size needed.
(b) Find the minimum sample size needed, using a prior study that found that 65% of the respondents said they support
labeling legislation for GMOs.
(c) Compare the results from parts (a) and (b).
...
(a) What is the minimum sample size needed assuming that no prior information is available?
n =
(Round up to the nearest whole number as needed.)
The table available below shows the costs per mile (in cents) for a sample of automobiles. At a = 0.05, can you conclude that at least one mean
cost per mile is different from the others?
Click on the icon to view the data table.
Let Hss, HMS, HLS, Hsuv and Hмy represent the mean costs per mile for small sedans, medium sedans, large sedans, SUV 4WDs, and minivans
respectively. What are the hypotheses for this test?
OA. Ho: Not all the means are equal.
Ha Hss HMS HLS HSUV HMV
B. Ho Hss HMS HLS HSUV = μMV
Ha: Hss *HMS *HLS*HSUV * HMV
C. Ho Hss HMS HLS HSUV =μMV

Question: A company launches two different marketing campaigns to promote the same product in two different regions. After one month, the company collects the sales data (in units sold) from both regions to compare the effectiveness of the campaigns.
The company wants to determine whether there is a significant difference in the mean sales between the two regions. Perform a two sample T-test
You can provide your answer by inserting a text box and the answer must include:
Null hypothesis,
Alternative hypothesis,
Show answer (output table/summary table), and
Conclusion based on the P value.
(2 points = 0.5 x 4 Answers)
Each of these is worth 0.5 points. However, showing the calculation is must. If calculation is missing, the whole answer won't get any credit.
