Park rangers are analyzing the proportion of raccoons that are infected with distemper virus in a park. The rangers sampled 125 raccoons using a catch and release protocol. 8 of the raccoons had distemper virus in them. Obtain a confidence interval for the proportion of raccoons that are infected with distemper virus in the park. Use ? 0.01.

How many raccoons should be caught and released for a study that requires a 1.69% of error at the same level of significance?

Identify the true statement.

I. If 536 are observed in the park, at least 4 of them are likely to be infected with distemper virus with 99% certainty.

II. If 536 are observed in the park, at most 65 of them are likely to be infected with distemper virus with 1% certainty.

III. If 536 are observed in the park, at least 4 of them are likely to be infected with distemper virus with 1% certainty.

IV If 536 are observed in the park, at least 65 of them are likely to be infected with distemper virus with 99% certainty.

A. I and II only

B. IV only

C. I only

D. III and IV only

    Confused on this problem as i'm getting mixed answers regarding this question. Is option 1 false because immortalisation requires whole episomal form of EBV and 9 proteins and here we are transfecting with only one protein 2? However, I read in an article that "Lymphoblastoid cell lines (LCLs) are human B cells latently infected and immortalized by Epstein-Barr virus (EBV). A mini-EBV plasmid that consists of less than half the EBV genome can still immortalize B cells in vitro." which...

    Is option 1 true or false? Transfected B cells will not become immortalized.

Earlier in the problem it states "B lymphocytes inf. with EBV & grown in vitro are immortalized & termed LCL which contain...

    1. A hypothetical investigation on rider satisfaction with a particular public transit system serving commuting residents of British California (BC) and Prince Edward’s County (PEC) offers some interesting findings. The proportion of commuters from BC that indicated low satisfaction with the transit system’s service in the 2018 calendar year was 65 percent, and the proportion from PEC was 70 percent. These point estimates were based on samples of 5,380 BC commuters and 6,810 PEC commuters, whose system-using commuters number in...
