Mean (Xbar) = Sum of data/ Number of data = 1.72
Standard deviation ( σ ) = ⎷∑(xi−Xbar)2 / (n−1)
∑(xi−Xbar)2 = 1.088
σ = ⎷∑(xi−Xbar)2 / (n−1) = √1.088/(5-1) ≈ 0.5215

The quality control manager at a light bulb factory needs to estimate the mean life of a large shipment of light bulbs. The standard deviation is 92 hours. A random sample of 64 light bulbs indicated a sample mean life of 360 hours. Complete parts (a) through (d) below. that the lightbulbs have a mean life of 410 hours. c. Must you assume that the population light bulb life is normally distributed? Explain. O A. Yes, the sample size is...
The quality control manager at a computer manufacturing company believes that the mean life of a computer is 120 months, with a standard deviation of 10 months. If he is correct, what is the probability that the mean of a sample of 90 computers would be less than 117.13 months? Round your answer to four decimal places.
The quality control manager at a computer manufacturing company believes that the mean life of a computer is 83 months, with a standard deviation of 99 months. If he is correct, what is the probability that the mean of a sample of 78 computers would be less than 82.06 months? Round your answer to four decimal places.
The quality control manager at a computer manufacturing company believes that the mean life of a computer is 117 months with a standard deviation of eight months if he is correct what is the probability that the mean of a sample of 52 computers would be less than 115. 46 months round your answer to four decimal places
The quality control manager at a light bulb factory needs to estimate the mean life of a large shipment of light bulbs. The standard deviation is 98 hours. A random sample of 49 light bulbs indicated a sample mean life of 300 hours. (a) Construct a 99% confidence interval estimate for the population mean life of light bulbs in this shipment. The 99% confidence interval estimate is from a lower limit of 263.9 hours to an upper limit of 336.1...
Confidence Interval The quality-control manager at a light bulb factory needs to determine whether the mean life of a large shipment of light bulbs is equal to 375 hours. The population standard deviation is 120 hours. A random sample of 64 light bulbs indicates a sample mean life of 350 hours. 1. At the 95% confidence level, what is the critical value? 39. What is the confidence interval based on this data? 2. Is there evidence that the mean life...
A quality control expert at Glotech computers wants to test their new monitors. The production manager claims they have a mean life of 75 months with a standard deviation of 5 months. If the claim is true, what is the probability that the mean monitor life would be less than 74.4 months in a sample of 85 monitors? Round your answer to four decimal places.
A quality control expert at Glotech computers wants to test their new monitors. The production manager claims they have a mean life of 94 months with a standard deviation of 9 months. If the claim is true, what is the probability that the mean monitor life would be greater than 93.5 months in a sample of 111 monitors? Round your answer to four decimal places
this problem requires PhStat solution. The quality-control manager at a compact fluorescent light bulb (CFL) factory needs to determine whether the mean life of a large shipment of CFLs is equal to 7,500 hours. The population standard deviation is 1,000 hours. A random sample of 64 CFLs indicate a sample mean life of 7,250 hours. 1. At 0.05 level of significance, state your decision. 2. Using the critical value approach, is there evidence that the mean life is different from...
