A delivery service places packages into large containers before flying them across the country. These filled containers vary greatly in their weight. Suppose the delivery service’s airplanes always transport two such containers on each flight. The two containers are chosen so their combined weight is close to, but does not exceed, a specified weight limit. A random sample of flights with these containers is taken, and the weight of each of the two containers on each selected flight is recorded. The weights of the two containers on the same flight (a) will have a correlation of 0 (b) will have a negative correlation (c) will have a positive correlation that is less than 1 (d) will have a correlation of 1

A restaurant manager is planning a new layout for the tables in his store. He will be placing tables of 2, tables of 4, and tables of 6 throughout the dining room. To help him decide how many of each he needs, he decides to keep track of all table requests by customers during a 2-week period. Which measure of central tendency would BEST indicate the typical table size needed?

Can someone please help? Thank you.

Many times we collect samples of data from the bigger population because the population is too large to use....because of time, cost, and ease. But, the best samples are a true reflection of the bigger population data. This Unit discussed several different sample types. Please define and then discuss how you might collect each of the following samples from your own organization: Simple Random Sample Stratified Random Sample Cluster Random Sample Which of the these three would likely give you the best reflection of the population data?

A. Find the first quartile B. Find the 2nd quartile C. Find the 3rd quartile

A biologist wants to determine if different temperatures (15oC, 25oC, or 35oC) and amounts of sunlight (partial or full) will affect the growth of plants. He will test each combination of temperature and sunlight by randomly assigning 15 plants to each of the combinations. What type of sampling is described in this study? one sample paired data two samples more than two samples

Some students are sampled at random from the cohort at a certain university and their heights recorded. The university has a student cohort of 1000, and 100 students are sampled. Thirty students are 175cm, thirty are 160cm, fifteen are 163cm, ten are 180cm, ten are 158cm, and five are 170cm. To three significant figures, how many resamples of size 100 can one make from this data? 4.53 × 1058 3.72trillion 2.63 × 1051 135million 3.72 x 1048

A quarterback  threw 1 interception in his first game, 2 interceptions in his second game, and 5 inter-ceptions in his third game, and then he retired. Consider the values1, 2, and 5 to be a population. Assume that samples of size 2 are randomly selected (with replacement) from the population. List  the  9  different  possible  samples,  and  find  the  mean  of each sample.

Determine u, and o; from the given parameters of the population and sample size. u = 84, o = 8, n = 64

Suppose a certain retailer sells several models of refrigerators. A random sample of the models sold by this retailer and their corresponding cubic feet (cu. ft.) and list price can be found below. Model Model 1 Model 2 Model 31 with Thru-the-Door Ice and Water. Model 4 Model 5 Model 6 with Thru-the-Door Ice and Water Model 7 Model 8. Model 9 with Thru-the-Door Ice and Water Model 10 with Thru-the-Door Ice and Water Model 11 with Thru-the-Door Ice and Water Model 12. Model 13 with Thru-the-Door Ice and Water Model 14 Model 14 Model 15 Model 16 with Thru-the-Door Ice and Water Model 17 Model 18 with Thru-the-Door Ice and Water Model 19 with Thru-the-Door Ice and Water Model 20 with Thru-the-Door Ice and Water Model 21 Cu.Ft.
