A large shipping company wants every order to arrive within the delivery time they give the customer. They plan to take a random sample of orders to construct a one-sample interval to estimate what proportion of all orders arrive within their delivery window. They will use a confidence level of 95%, percent, and that the margin of error exceeds 4 percentage points. The data above suggests that about 34% of orders arrive within their delivery time. Assuming that the previous estimate for the proportion is 0.34, what is the smallest sample size necessary to obtain the desired margin of error? Select one: a. The smallest sample size necessary to obtain the desired margin of error is 380 b. The smallest sample size necessary to obtain the desired margin of error is 539 ° C. The smallest sample size needed to obtain the desired one is 11 d. The smallest sample size needed to obtain the desired margin of error is the smallest required to obtain the desired margin of error.
Allen's hummingbird (Selasphorus sasin) has been studied by zoologist Bill Alther.t Suppose a small group of 20 Allen's hummingbirds has been under study in Arizona. The average weight for these birds is x = 3.15 grams. Based on previous studies, we can assume that the weights of Allen's hummingbirds have a normal distribution, with o = 0.32 gram. (a) Find an 80% confidence interval for the average weights of Allen's hummingbirds in the study region. What is the margin of error? (Round your answers to two decimal places.) lower limit upper limit margin of error (b) What conditions are necessary for your calculations? (Select all that apply.) O normal distribution of weights Oo is known O n is large O o is unknown O uniform distribution of weights (c) Interpret your results in the context of this problem.
