1. The simple random sample of the ages of children entering a carnival yields the following results: ages 5. 8, 10, 1, 12, 14 years old. Find the following: a. Sample mean b. Standard deviation 2. Bilog Light Manufacturing Company provided estimates of the light expectancy of their newly manufactured LED LITES in their brochures. A single random sample of LED LITES shows the following useful life in thousand hours: 55. 7D, 52, 65, 75, 85, 45, 50, 75. nd: a. Mean useful life b. Standard deviation of the useful life Step 2. Determine the mean of the sampling distribution. Use the property that HX - H Step 3. Solve the standard deviation of the sampling distribution. Use the property that Conclusion:ACTIVITY 2: THE weight of female MMMHS SHS students are normally distributed with mean of 65 kgs and standard deviation of 2 kgs. If 100 samples consisting of 25 students each are drawn from the population, what would be the mean and standard deviation of the computed sampling distribution of the means?Activity. Solve and Describe The scores of individual students on a national achievement test have a normal distribution with mean 20.8 and a standard deviation of 1.9. At Feliciano Delos Santos High School, 84 students took the test.If the scores of the students at this school have the same distribution as the national scores, how will you describe the sampling distribution of the scores of these students? Assume that the population is infinite. Step 1. Identify the given information
