Find the 95% confidence interval for estimating the population mean μ If sample mean X = 50, sample size n= 60 and population standard deviation σ is known to be 10.
To calculate 95% confidence interval we must multiply the standard error by 3, then add and subtract the result to the best estimate. add and subtract the standard error to the best estimate. multiply the standard error in y-intercept by 2, then add and subtract the result to the slope of the graph. multiply the standard error by 2, then add and subtract the result to the best estimate.
The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 93 pounds. A random sample of 70 newly manufactured cables has a mean breaking strength of 1800 pounds. Based on this sample, find a 99% confidence interval for the true mean breaking strength of all cables produced by this manufacturer. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places.
The average monthly gas bill of a random sample of 43 residents of a city is $172 with a standard deviation of $24.5. Assume the gas bills are normally distributed. Construct a 90% confidence interval for the population mean monthly gas bills of all residents.

With 80% confidence, for sample proportion 0.40 and sample size 22, what is the upper confidence limit with 2 decimal places?
A random sample of 225 adults was given an IQ test. It was found that 112 of them scored higher than 100. Based on this, compute a 90% confidence interval for the proportion of all adults whose IQ score is greater than 100. Then find the lower limit and upper limit of the 90% confidence interval.Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places.

Construct a 95% confidence interval for the mean ounce of caffeine consumption of all students. What can we assert with 95% confidence interval about the possible size of our error if we estimate the mean ounce of caffeine consumption of all students to be 14.4? Show solution with formulas
In a factory the 95% confidence interval of the mean net weight of the chocolates produced was estimated. Based on a random sample of 400 chocolates the mean net weight is between 99 grams and 101 grams. Give the maximum error of the estimate in grams.
