The mean arrival rate of flights at O'Hare Airport in marginal weather is 195 flights per hour with a historical standard deviation of 16 flights. To increase arrivals, a new air traffic control procedure is implemented. In the next 30 days of marginal weather, the mean arrival rate is 196 flights per hour.

199 188 174 176 202 195 195 208 222 221
(a) Set up a right-tailed decision rule at a =.025 to decide whether there has been a significant increase in the mean number of arrivals per hour.
(b) Carry out the test and make the decision. Is it close? Would the decision be different if you used a = .01?
(c) What assumptions are you making, if any? Flights

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
