A town council wants to estimate the proportion of residents who are in favor of a proposal to upgrade the computers in the town library. A random sample of 100 dants was selected and 7 of those selected indicated that they were in favor of the proposals appropriate to assume that the sampling distribution of the sample proportion is approximately normal
1.No, because the sample is not large enough to satisfy the normality conditions
2.No, because the size of the population is not known.
3.Yes, because the sample was selected at random
4.Yes, because sampling distributions of proportions are modeled with a normal model
5.Yes, because the sample is large enough to satisfy the normality conditions
