Perform a hypothesis test at a 5% level of significance to see if the proportion of white individuals who are fatally shot by police is less than the total proportion of white individuals in the United States, which is approximately 60.1% according to the U.S. census bureau.  State your null and alternative hypotheses in mathematical notation

Total DVD and Blu-ray disc sales in 2009 were $8.72 billion. For the purposes of this problem, you will combine DVD and Blue-ray disk sales into one category of DVD sales. A study by In-Stat predicted that "physical disc sales will decline by $4.7 billion by 2014," and that "streaming, on the other hand, should grow from its current $2.2 billion to $6.3 billion over the same time period (2009–2014). d. Write an equation that represents the linear model for streaming videos. Let S = the total sales of streaming videos in billions of dollars, and t = the number of years after 2009. e. In what year do the models predict streaming video sales to exceed DVD sales?
