Question description

Stats

I need help with this assignment. I submitted once but my calculations were wrong. Can yhou pleas eshow me in excel how to calculate? Thanks.

You may assume that these respondents represent a simple random sample of all potential respondents within the community and that the population is large enough that application of the finite population correction would not make an appreciable difference in the results.

  1. Item C in the description of the data collection instrument lists variables 7, 8, and 9, which represent the respondent’s general attitude toward each of the three shopping areas. Each of these variables has numerically equal distances between the possible responses, and for purposes of analysis they may be considered to be of the interval  scale of measurement.

    a. Determine the point estimate, then construct the 95% confidence interval for = the average attitude toward Springdale Mall. What is the maximum likely error in the point estimate of the population mean?

    b. Repeat part (a) for and , the average attitudes toward Downtown and West Mall, respectively.

  2. Given the breakdown of responses for variable 26 (sex of respondent), determine the point estimate, then construct the 95%  confidence  interval for = the population proportion of males. What is the maximum likely error in the point estimate of the population proportion?
  3. Given the breakdown of responses for variable 28 (marital status of respondent), determine the point estimate, then construct the 95% confidence interval for  = the population proportion in the “single or other” category.  What is the maximum likely error in the point estimate of the population proportion?
