A new study of 170 lung cancer patients found that 123 of them died within a year, while undergoing a new treatment. Based on this sample data, compute 88% confidence limits to complete the statement below. Use Normal distribution instead of t: E=zα2.(pqn)−−−−−√ Give values as percentages, rounded to two digits after the decimal point. Do not include the % symbol in your answer.

in a random sample of 150 turtles, it is found that 30 have light-coloured shells. let p be the population proportion of turtles that have light-coloured shells. i) using our observations as a pilot study, estimate the sample size needed to construct confidence interval such that we are 90% confident that the sample proportion will be within 0.01 of the true population proportion p. ii) if we were to test the hypothesis H0 : p <= 0.15,H1 ; p >...

A poll found that 53% of a sample of 1170 teens in a certain large country go online several times a day. (Treat this sample as a simple random sample.) Complete parts a through e below. a) Find the margin of error for this poll if we want 90% confidence in our estimate of the percent of teens in the country who go online several times a day. 24% (Round to one decimal place as needed.) b) Explain what the...

Problem: Proportion of "Cured” Cancer Patients: How Does Canada Compare with Europe? Lung cancer remains the leading cause of cancer death for both Canadian men and women, responsible for the most potential years of life lost to cancer. Lung cancer alone accounts for 28% of all cancer deaths in Canada (32%. in Quebec). Most forms of lung cancer start insidiously and produce no apparent symptoms until they are too far advanced. Consequently, the chances of being cured of lung cancer...

A new idea for treating advanced melanoma, the most serious kind of skin cancer: Genetically engineer white blood cells to better recognize and destroy cancer cells, and then infuse these cells into patients. The subjects in a small initial study of this treatment were 1111 patients whose melanoma had not responded to existing treatments. One question was how rapidly the new cells would multiply after infusion, as measured by the doubling time (in days). The doubling times are provided: 1.41.4...

7. A study was conducted to investigate the effectiveness of a new drug for treating Stage 4 AIDS patients. A group of AIDS patients was randomly divided into two groups. One group received the new drug; the other group received a placebo. The difference in mean subsequent survival (those with drugs - those without drugs) was found to be 1.04 years and a 95% confidence interval was found to be 1.04 ± 2.37 years. Based upon this information: Select one...
