I need help with 1 a and b
At the moment this question was written, 9.8% of Californians had received their first vaccine shot for COVID-19, while 8.5% of Californians had received both of their COVID-19 vaccination shots. The rest of the population of California had not received any COVID-19 vaccination shot at all. For all parts below, be sure to label your axes in any sketches and/or graphs!

The rest of the population of California had not received any COVID-19 vaccination shot at all. For all parts below, be sure to label your axes in any sketches and/or graphs!
- (4 pts) Sketch and/or attach a graph from StatCrunch for the population distribution for the number of COVID-19 vaccination shots Californians have received at the time of this writing.
- (4 pts) Use StatCrunch to sample from this population, using a sample size of 500 randomly selected Californians. Compute the sample proportions for each category and sketch and/or attach a graph of the results of your sample.
- (3 pts) What is an observational unit for your results in part (b)?
- (6 pts) Now suppose that 150 Statisticians throughout California each collected a random sample of 500 Californians and recorded how many COVID-19 vaccination shots they had received. Then each of them reported the percentage of Californians who had received both dosages of the COVID-19 vaccine shot. Those percentages are shown in the graph below. What is an observational unit for this graph? Describe the shape, center, and spread of the sampling distribution.

- (3 pts) Show where your sample proportion from part (b) lies on the graph in part (d). Would you consider your sample an expected or unexpected result? Support your reasoning.
