The pie chart shows the percentage of votes received by each candidate in the student council presidential election. Use the pie chart to answer the question.  There were 400 votes cast in the election.  (Ignore the fact that the graph says 300, assume it was 400.) What was the number of votes received by Ben?  [answer1] What was the number of votes received by the person with the highest number? [answer2]

Consider the following Stem and Leaf Plot: What is the minimum value in the graph?

A national survey asked people, “How often do you eat out for dinner, instead of at home?”  The frequencies were as follows.     What was the relative frequency of the response “rarely?”  Give your answer to three decimal places.

The graph below represents the relative frequency of responses when a sample of 128 people were asked how many cars are owned in their household.  About how many of those in the sample said they have 3 cars in their household?

The author surveyed some of the students in one of his statistics classes about the numbers of hours they work per week.

In 2020, 15.8% of California residents were aged 65 year or older.  A random sample of 15 California residents is chosen.  Find each of the following probabilities.   Round to three decimal places.  What is the probability that exactly 4 in the sample are aged 65 or older?  [exact] What is the probability that at most 4 in the sample are aged 65 or older?  [least]

The prices of Honda CRV cars are normally distributed with a mean of $33,300 and a standard deviation of $3000. If one Honda CRV is randomly chosen, what is the probability that its price is less than $28,000.?  Round your response to 4 decimal places. [q1] 76% of Honda CRV prices are between [lower] and [upper].  Round to the nearest dollar.  Suppose a random sample of 40 Honda CRVs is chosen.   Describe the sampling distribution of the mean for samples of size 40.  Be sure to address the shape, the mean of the sampling distribution and the standard error of the mean.  Where rounding is necessary, round to the nearest dollar.   The sampling distribution of the mean is [shape] with a mean of [mean]  and standard error of [se].   What is the probability that a random sample of 40 Honda CRV’s results in a mean price of more than $34,200?  The probability is [prob].  (Round to 4 decimal places) Complete the following sentence to interpret this probability.  If [100s] were chosen from this population, we’d expect about [number] to have a mean price of more than $34,200. 

A random sample of 2301 people living in Los Angeles indicated that 105 agreed with the statement, “I would like to change jobs within the next year.” Complete the following based on this information using only definitions provided in this class.  It is [un] for a person living in Los Angeles to agree with the statement because the probability of [prob] is [less].
