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.)

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
