In Exercises 1–5, use the following survey results: Randomly selected subjects were asked if they were aware that the Earth has lost half of its wildlife population during the past 50 years. Among 1121 women, 23% said that they were aware. Among 1084 men, 26% said that they were aware (based on data from a Harris poll).
Biodiversity When using the given sample data to construct a 95% confidence interval estimate of the difference between the two population proportions, the result of (−0.0659, 0.00591) is obtained from technology.
a. Express that confidence interval in a format that uses the symbol <.
b. What feature of the confidence interval is a basis for deciding whether there is a significant difference between the proportion of women aware of the statement and the proportion of men who are aware?
A study, which randomly surveyed 3,700 households and drew on this information from the IRS, found that 79% of households have conducted at least one IRA rollover from an employer-sponsored retirement plan. Suppose a recent random sample of 90 households in a certain county was taken and respondents were asked whether they had ever funded an IRA account with a rollover from an employer-sponsored retirement plan. Based on the sample data below, can you conclude at the 0.10 level of significance that the proportion of households in the county that have funded an IRA with a rollover is different from the proportion for all households reported in the study?
77 respondents said they had funded an account; 13 respondents said they had not
If we were to ask for a minimum sample size for a 94% level of confidence what would the value for z-sub-c be?
