Cell Phones and Cancer A study of 420,095 Danish cell phone users found that0.0321% of them developed cancer of the brain or nervous system. Prior to this study of cellphone use, the rate of such cancer was found to be 0.0340% for those not using cell phones. The data are from the Journal of the National Cancer Institute. a. Use the sample data to construct a 90% confidence interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system. b. Do cell phone users appear to have a rate of cancer of the brain or nervous system that is different from the rate of such cancer among those not using cell phones? Why or why not?
Pottery Archaeologists can use the chemical composi-tion of clay found in pottery artifacts to determine whether different sites were populated by the sameancient people. They collected five samples of Romano–British pottery from each of two sites in Great Britainand measured the percentage of aluminum oxide in each.Based on these data, do you think the same people usedthese two kiln sites? Base your conclusion on a 95%confidence interval for the difference in aluminum oxidecontent of pottery made at the sites. (A. Tubb, A. J. Parker,and G.

The data below are yields for two different types of corn seed that were used on adjacent plots of land. Assume that the data are simple random samples and that the differences have a distribution that is approximately normal. Construct a 95% confidence interval estimate of the difference between type 1 and type 2 yields. What does the confidence interval suggest about farmer Joe's claim that type 1 seed is better than type 2 seed?Type 1 2143 2024 2142 2433 2142 2034 2211 1484 Type 2 2089 1924 2078 2467 2132 1949 2197 1482
A large automobile insurance company selected samples of single and married male policyholders and recorded the number who made an insurance claim over the preceding three-year period. Single Policyholders Married Policyholders n1=550 n2=1,000 Number making claims = 110 Number making claims = 150 a. Use a=0.05 Test to determine whether the claim rates differ between single and married male policyholders. z-value (to 2 decimals) p-value (to 4 decimals) b. Provide a 95% confidence interval (to 4 decimals) for the difference between the proportions for the two populations. Enter negative answer as negative number. ( , )
Caffeine in Soft Drinks Listed below are measured amounts of caffeine (mg per 12 oz of drink) obtained in one can from each of 20 brands (7UP, A&W Root Beer, Cherry Coke, …, TaB). Use a confidence level of 99%. Does the confidence interval give us good information about the population of all cans of the same 20 brands that are consumed? Does the sample appear to be from a normally distributed population? If not, how are the results affected?
A random sample of 500 males included 215 that approved of the performance of a President. A random sample of 500 females included 185 that approved of the performance of a President. Determine each of the following parts that will lead you to construct a 95% confidence interval for the overall difference in the percentage of males and females that approve of the President's performance. Group one males, group 2 females Calculate p-hat 1 and q-hat 1, Calculate p-hat 2 and q-hat 2 , Calculate (p-hat 1 - p-hat 2) And Find the critical z-score for a 95% level of confidence

A manufactuter of washing machine plans to introduce entry level new model to boost up his sale. the company has hired two independent market research firms MRA and MRB, to estimate the proportion of households that currently use washing machines. MRA conducted the survey of 400 households and it found 20% of the house holds currently using washing machines. MRB conducted survey of 600 households and found that 18% of house holds currently using washing machines. A)develop 95% confidence intervals for the two surveys B)explain the reason for difference between two surveys
