Use descriptive statistics to summarize the data from Fuentes’ study. Based on your de- scriptive statistics, what are your preliminary conclusions about penetration of Fuentes’ Candied Bacon Potato Chips in grocery stores across its eight U.S. sales regions? Use the data from Fuentes’ study to test the hypothesis that the proportion of grocery stores that currently carries Fuentes’ Candied Bacon Potato Chips is equal across its eight U.S. sales regions. Use a 5 .05. Do the results of your hypothesis test provide evidence that penetration of Fuentes’ Candied Bacon Potato Chips in grocery stores differs across its eight U.S. sales regions? In which sales region(s) is penetration of Fuentes’ Candied Bacon Potato Chips lower or higher than expected? Use the Marascuilo pairwise comparison procedure at a 5 .05 to test for differences between regions.

A national vital statistics report indicated that 3% of all births produced twins. Researchers are curious about the proportion of twin births among teenage mothers. A large hospital reported a sample of 469 births from teenage mothers found 7 sets of twins. Is the proportion of twin births among teenage mothers different from the overall figure? Use a 10% significance level.

TechBuzz is an IT company that monitors the status of large data warehouses. According to TechBuzz, last year the majority of the data servers used by energy-based companies were over-utilized. A sample of 190 servers (all used by energy-based companies) showed that 142 were over-utilized, 12 were used efficiently, and 36 were underutilized. a. What is the point estimate of the proportion of the servers that were under-utilized? b. Determine the margin of error and provide a 95% confidence interval for the proportion of the servers that were over-utilized. c. What is the minimum sam

A newspaper infographic titled "Social Media Jeopardizing Your Job?" summarized data from a survey of 1,850 recruiters and human resource professionals. The infographic indicated that 54% of the people surveyed had reconsidered a job candidate based on his or her social media profile. Assume that the sample is representative of the population of recruiters and human resource professionals in the United States. USE SALT (a) Use the given information to estimate the proportion of recruiters and human resource professionals who have reconsidered a job candidate based on his or her social media profile using a 95% confidence interval. (Round your answers to three decimal places.) Give an interpretation of the interval in context. O There is a 95% chance that the true proportion of recruiters and human resource professionals who have reconsidered a job candidate based on his or her social media profile falls directly in the middle of this interval. O There is a 95% chance that the true…

The IQ scores for a random sample of subjects with medium lead levels in their blood and another random sample of subjects with high lead levels in their blood are given below. Use a 0.05 significance level to test the claim that subjects with medium lead levels have full IQ scores with a higher median that the median full IQ score for subjects with high lead levels. Does lead level appear to affect full IQ scores? Click the icon to view the data table. First define the null and alternative hypotheses. Ho: H₁: Data Table Let the medium lead level be sample 1.
