According to Crestmont Research, the stock market has been up in 53.7% of all trading days over the past fifty years. A stock is up if the price per share increases in value day-over-day. An investor wondered whether the proportion of days Amazon stock was up differed from the market. The following data represent a random sample of 200 trading days, where 1 indicates the stock was up for the day (an increase in the price) and 0 indicates the stock was not up for the day (either down or unchanged). Does this sample evidence suggest the movement of Amazon stock is different from the stock market? Use the a= 0.01 level of significance. Complete parts (a) through (h). Click the icon to view the sample of trading days. QUELEID (a) Determine the null and alternative hypotheses if we want to know if the evidence suggests the movement of Amazon stock is different from the stock market. Ho P = H₁: P # (Type integers or decimals. Do not round.)
