Only b.ii, iii and iv please. The output of a solar panel (photovoltaic) system depends on its size. A manufacturer states that the average daily production of its 1.5 kW system is 6.6 kilowatt hours (kWh) for Perth conditions. A consumer group monitored this 1.5 kW system in 20 different Perth homes and measured the average daily production by the systems in these homes over a one month period during October. The data is provided here. (a) Analyse the consumer group’s data to test if the manufacturer’s claim of an average of 6.6 kWh per day is reasonable. State appropriate hypotheses, assumptions and decision rule at α = 0.10. What conclusions would you report to the consumer group? Hint: You will need to find Descriptive Statistics first.) (b) If 48 homes in the central Australian city of Alice Springs had this system installed and similar data wascollected, in order to assess whether average daily production in Alice Springs exceeded 6.6 kWh, (i) what would the alternate hypothesis…

If quantitative, estimate the range. e) In Figure 2.85(a), if we only consider cases in Group A, does the association between Variable1 and Variable2 appear to be positive or negative? How about in Group B? Group C? Group D? (f) Figure 2.85(b) shows the same scatterplot as Figure 2.85(a) with regression lines added within each of the four groups.

1. (10 ) According to the PayScale data from 2021, the average starting salaries by college major for bachelor's degree are as follows: $70,600 for mechanical engineering, $56,700 for economics, $43,500 for chemistry, and $47,000 for philosophy. In order to estimate the true difference in the average starting salaries by college major in 2022, 60 graduates with these four majors from the class of 2022 were contacted and questioned about their starting salaries. Propose a regression model with dummy variables that could be used to investigate if starting salaries are different by college major and interpret all the coefficients in the model. 0.000
