A scientist estimates that the mean nitrogen dioxide level in a city is greater than 30 parts per billion. To test this estimate, you determine the 29 17 44 23 22 35 23 17 25 27 23 nitrogen dioxide levels for 31 randomly selected days. The results (in parts 35 27 32 33 39 30 18 21 43 40 30 per billion) are listed to the right. At a= 0.12, can you support the scientist's estimate? Complete parts (a) through (e). 30 27 34 14 20 32 33 39 24 (a) Write the claim mathematically and identify H, and H,. Choose from the following. O A. H,: µ= 30 (claim) H p> 30 O B. Ho: µ= 30 H: p> 30 (claim) OC. H,: H< 30 H3: p2 30 (claim) O D. H,: µs 30 (claim) H p> 30 O E. H,: µ2 30 (claim) H: p< 30 OF. Ho: us 30 H u> 30 (claim)
