I need help on step 6

-_ Step 5 | (c) Interpret your reslts in the context of this problem. ' Recall that if /i is a random variable, the endpoints /i + E are also random variables. After the confidence interval is numerically fixed for a specific sample, it either does or does not contain g. lnterpret your results in the context of this problem I@ H We are 80% confident that the true average welght of Al|en s hummmgblrds falls wsthin this interval. f The probability that this interval contains the true average weight of Allen's hummingbirds is 0.80. | | !. \\We are 20% confident that the true average weight of Allen's hummingbirds falls within this interval. | | The probability that this interval contains the true average weight of Allen's hummingbirds is 0.20. \\ \\. | 0% confidence level with a maximal margin of error E = 0.11 for the mean | | (d) Find the sample size necessary for i In 8 welghts of the hummingbirds. | Recall that the formula for finding the sample size n for estimating u when o is known is 2 = (ZCG) i E T where E is the specified maximal margin of error, is the population standard deviation, and z_is the critical value from the normal distribution for the desired confidence level c. Use the formula above to find the sample size necessary for an 80% confidence level with a ma ximal margin of error of = 0.11. Recall that z_= 1. 28 and = 0.33.
