An environmental group is interested in what percentage of Americans consider climate change an immediate threat to humanity. From a representative list of 5742 American citizens, they randomly sampled 30; all responded to their questions. They will consider the sample proportion of respondents that agree climate change is an immediate threat to humanity. Previously, 35% of Americans considered climate change an immediate threat to humanity; assume this has not changed. Is it appropriate to use normal distribution to describe the sampling distribution of sample proportion
