The price of a zazio camera at a national chain store is $181. a new statistics student decided to test the hypothesis that you can buy that same camera online for less than you can buy it at the chain store. he decided to test it at a level of significance of .05 since that level is the most common level. he looked up the price of that camera on 10 different websites. here are the prices that he found: 157 181 177 183 157 181 182 177 163 177What is the null hypothesis? (Remember that the null hypothesis contains an equal sign.)
