- Find the mean of the sampling distribution of sample means using the given information. Round to one decimal place, if necessary. μ=65 and σ=12; n=16Consider a sample data with x=25 and s=2. Compute a chebyshev’s interval for which at least 89% of the data will lie?A manufacturing company claims that the average lifetime of their incandescent lamps is 1300 hours. A random sample of 16 lamps are tested, and their lifetimes, in hours, are shown below:
- When considering different sampling methods, stratified sampling includes the steps: Select the correct answer below: divide the population into groups; use simple random sampling to identify a proportionate number of individuals from each group list the members of the population; use simple random sampling to salect a starting point in the population; let k = (number of individuals in the population)/(number of individuals needed in the sample); choose every kth individual in the list starting with the one that was randomly selected O identify individuals of the population that are easily accessible; obtain data from these individuals use simple random sampling to select a set of groups; every individual in the chosen groups is included in the sample FEEDBACK MORE INSTRUCTION INTL V O 9:The mean number of credits earned by students is claimed to be 30.0.
