In a study to estimate the proportion of residents in a certain city and its suburbs who favor the construction of a nuclear power plant, it is found that 59 of 100 urban residents favor the construction while only 39 of 100 suburban residents are in favor. Is there a significant difference between the proportions of urban and suburban residents who favor construction of the nuclear plant? Make use of a P-value.

Transcribed Image Text:Five samples of a ferrous-type substance were used to determine if there is a difference between a laboratory chemical analysis and an X-ray fluorescence analysis of the iron content. Each sample was split into two
subsamples and the two types of analysis were applied, with the accompanying results. Assuming that the populations are normal, test at the 0 10 level of significance whether the two methods of analysis give, on the average,
the same result
