Question
A soft drink company wanted to know whether their new drink “PopFizzy” could maintain its fizziness from the first to last sip. They recruited 100 volunteers to rate the fizziness of their first sip, and again for their last sip (0 = not fizzy at all, 9 = very fizzy). The results revealed an F value of 16.50. What is the dftreatment and dferror?
dftreatment = 2, dferror = 98 |
||
dftreatment = 1, dferror = 98 |
||
dftreatment = k - 1, dferror = N - k |
||
dftreatment = 1, dferror = 99 |

The aircraft can carry 40 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6,250 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 6,250 lb / 40 = 163 lb. What is the possiblity that the aircraft is overloaded? Should the pilot take any action to correct an overloaded aircraft? Assume that the weights of men are normally distributed with a mean of 177.3 lb and a standard deviation of 39.3 The probability is approximatelyarrow_forward

- A Biomedical engineer is measuring how much current is needed to stimulate the nerve of a rat to create a muscle function. He is measuring 5 rats and wants to evaluate if less current is needed to stimulate a young animal compared to an old animal. The mean of the current to stimulate young animals is 4.6mA. Meuasrements from trials on Old Rats: 6, 6, 12, 7, 8 (in mA) Can the engineer conclude that old rats need more current?arrow_forwardGinny’s professors conspired to all give a test on the same day.
