Question
In its Millennium Development Goals Report, the United Nations suggested that by the end of 2015 there will be 6.8 billion cell-phone subscription plans, and approximately 2.6 billion people will be connected to the Internet. We would like to assess if there is any evidence to suggest that the population proportion of households in Italy that are connected to the internet (p1) is greater than the population proportion of households in Brazil that are connected to the internet (p2). That is, to test the following theories using a 5% significance level: H0: p1 = p2 versus Ha: p1 > p2. To put this theory to the test, a large random sample of households in Italy and Brazil was obtained, and the number of households connected to the Internet was recorded for each. From this random sample, it is revealed that 49.39% of the sampled households in Italy are connected to the internet and 54.26% of the sampled households in Brazil are connected to the internet.
Based on the results, which of the following statements is (are) correct statements.
The results are statistically significant at a 1% level.
The results are statistically significant at a 1% level but not at a 5% level.
The results are statistically significant at a 5% level but not at a 10% level.
The results are not statistically significant at a 1% level.
The results are not statistically significant at a 5% level.
The results are not statistically significant at a 10% level.
Can't be determine because not enough information was provided.
Explanation / Answer
as from sample 49.39% of the sampled households in Italy is less than 54.26% of the sampled households in Brazil threore it can never support alternae hypothesis on any level of significance
hence correct option are:
The results are not statistically significant at a 1% level.
The results are not statistically significant at a 5% level.
The results are not statistically significant at a 10% level.
