Textbook Question
Chapter 3.1, Problem 1E
Each person in a nationally representative sample of 1252 young adults age 23 to 28 years old was asked how they viewed their financial physique (financial health) (“2009 Young Adults & Money Survey Findings,” Charles Schwab, 2009). “Toned and fit” was chosen by 18% of the respondents, while 55% responded “a little bit flabby,” and 27% responded “seriously out of shape.” Summarize this information in a pie chart. (Hint: See Examples 3.2 and 3.3.)

Can you help me solve problem 38 with steps im stuck.
How do the samples hold up to the efficiency test? What percentages of the samples pass or fail the test?
What would be the likelihood of having the following specific number of efficiency test failures in the next 300 processors tested?
1 failures, 5 failures, 10 failures and 20 failures.
The battery temperatures are a major concern for us. Can you analyze and describe the sample data? What are the average and median temperatures? How much variability is there in the temperatures? Is there anything that stands out?
Our engineers’ assumption is that the temperature data is normally distributed. If that is the case, what would be the likelihood that the Safety Zone temperature will exceed 5.15 degrees? What is the probability that the Safety Zone temperature will be less than 4.65 degrees?
What is the actual percentage of samples that exceed 5.25 degrees or are less than 4.75 degrees?
Is the manufacturing process producing units with stable Safety Zone temperatures? Can you check if there are any apparent changes in the temperature pattern? Are there any outliers? A closer look at the Z-scores should help you in this regard.

Total quarterly takings are in millions of Australian dollars. a. Perform inflation adjustment for Takings (using the CPI column), creating a new column in the tsibble called Adj Takings. b. For each state, fit a dynamic regression model of Adj Takings with seasonal dummy variables, a piecewise linear time trend with one knot at 2008 Q1, and ARIMA errors. c.
