Assuming that the population is normally distributed, construct a 95% confidence interval for the population mean, based on the following sample size of .n=7. 1, 2, 3, 4, 5, 6, and 15 <-----this is the data In the given data, replace the value 15 with 7 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval, in general. Find a 95% confidence interval for the population mean,...

7.3.49 Question Help Given a population in which the probability of success is p=0.35, if a sample of 300 items is taken, then complete parts a and b. a. Calculate the probability the proportion of successes in the sample will be between 0.32 and 0.37. b. Calculate the probability the proportion of successes in the sample will be between 0.32 and 0.37 if the sample size is 100 a. The probability the proportion of successes in the sample will be...
