3. Suppose that 15% of the 1750 students at a school have experienced extreme levels of stress during the past month. A high school newspaper doesn't know this figure, but they are curious what it is, so they decides to ask a simple random sample of 160 students if they have experienced extreme levels of stress during the past month. Subsequently, they find that 10% of the sample replied "yes" to the question. Assuming the true proportion is 15% what is the approx. prob that more than 10% of the sample would report that they experience extreme levels of stress during the past month

Assuming the true proportion is 15% what is the approx. prob that more than 10% of the sample would report that they experience extreme levels of stress during the past month 4. The average test scores in physics class is normally distributed with a std deviation of 5.4. 50 scores with a sample mean of 79 were selected at random. (a) find a 95% confidence interval for the population mean test score. (b) what is the value of margin error?
