QuestionMetal Tags on Penguins and Breeding Success A study was designed to test whether applying metal tags is detrimental to a penguin. The scientists studied the breeding success of the metal and electronic tagged penguins. Metal tagged penguins successfully produced offspring in 32%32 \% of the 122 total breeding seasons, while the electronic tagged penguins succeeded in 44%44 \% of the 160 total breeding seasons.
Construct a 90%90 \% confidence interval for the difference in proportion successfully producing offspring (pMpE\left(p_{M}-p_{E}\right. ). Let pMp_{M} be the proportion of penguins with metal tags that succeeded in breeding and pEp_{E} be the proportion of penguins with electronic tags that succeeded in breeding.
Round your answers to three decimal places.

Studdy Solution
The 90%90\% confidence interval for the difference in proportions (pMpE)(p_M - p_E) is approximately (0.215,0.025)(-0.215, -0.025).
