Question

A study investigated whether patients had unusually high body temperature the day after receiving a new vaccine. The study found that, with a sample of 64, the average body temperature of patients was 98.705 degrees F the day after getting the vaccine. The standard deviation of body temperature for that sample was about 0.330 degrees.

1) let’s continue on with a 90% confidence interval. What would be the standard error for our sample proportion, using the information we have from our sample to estimate that? Round to 3 decimal places

2) Remember that a 90% confidence interval will go 1.65 standard errors out in either direction. Calculate the lower bound of this 90% confidence interval for the true proportion of drug users who experience a skin rash as a side effect
