If we wish to have a 95% confidence interval, what would be the value of the confidence coefficient?

And..

Consider a sample mean of 46 calculated from a sample size of 51 drawn from a population of over 1000. Would it be appropriate to use the standard score table to look up the probability of a standard (z) score calculated on these data? Why or why not?

We wish to give a 95% confidence interval for the mean time it takes to complete a routine assembly task. To this end we obtain a random sample of 100 assembly times. We obtain a sample mean value of 15 minutes with a sample standard deviation of 5 minutes. Give the point estimate of the population average assembly time

Suppose we wish to estimate the mean heart rate, using a 95% confidence interval, for a par- ticular population. We observe 130 individuals to see a sample mean of 98.249 and a sample standard deviation of 0.733. We then find the tc-value, corresponding to the value on the t-distribution (d.f. = 130) so that the area to the left of it is equal to 95%, which ends up being: tc ≈ 1.656659. Next we compute the error and obtain our...
