A scientist estimates that the mean nitrogen dioxide level in a city is greater than 29 parts per billion. To test this estimate, you determine the nitrogen dioxide levels for 31 randomly selected days. The results (in parts per billion) are listed to the right. Assume that the population standard deviation is 11. At alphaequals0.12, can you support the scientist's estimate? Complete parts (a) through (e). 16 34 21 30 43 43 27 43 24 24 30 36 33 20 37 31 44 43 33 16 31 39 22 21 35 44 22 30 40 39 18 Question content area bottom Part 1 (a) Write the claim mathematically and identify Upper H 0 and Upper H Subscript a. Choose from the following. A. Upper H 0: muequals29 Upper H Subscript a: mugreater than29 (claim) B. Upper H 0: muless than or equals29 (claim) Upper H Subscript a: mugreater than29 C.
