The dataset cats is an R built-in dataset that is found in the MASS package. This dataset contains the heart and body weight measurements collected from a sample of 144 male and female domes- ticated adult cats that was to be used for digitalis experiments.

A manufacturing company glues one part to another part during the assembly of its final product. Either too much or too little glue presents a problem. It is important for the pressure of the glue nozzle (pounds per square inch) to be set correctly because it affects the amount of glue (ounces) that is applied. Ten applications are sampled and the following information collected: SSXX = 129.6 SSYY = 2.345 SSXY = 16.6 X bar = 25.2 Y bar = 2.05 What is the estimated y intercept?
See picture of table attached to answer, thank you Garrison Bay is a small bay in Washington state. A popular recreational activity in the bay is clam digging. For several years, this harvest has been monitored and the size distribution of clams recorded. Data for lengths and widths of littleneck clams (Protothaca staminea) were recorded by a method of systematic sampling in a study done by S. Scherba and V. F. Gallucci"The Application of Systematic Sampling to a Study of lnfaunal Variation in a Soft Substrate Intertidal Environment," Fishery Bulletin, Vol. 74, pp. 937-948). The data in Tables 8-4 and 8-5 give lengths and widths for 35 littleneck clams. (a) Use a calculator to compute the sample mean and sample standard deviation for the lengths and widths. Compute the coefficient of variation for each. (b) Compute a 95% confidence interval for the population mean length of all Garrison Bay littleneck clams. (c) How many more littleneck clams would be needed in a…

The average spent nationally on Christmas gifts in 2020 was reported to be $650 per person. Below is a random sample of gift givers from Iowa and what they spent in 2020. Is there sufficient evidence to conclude that Iowans spend less than the national average? Estimate the average amount spent by Iowans on Christmas gifts in 2020 with a 90%-CI. 700 450 400 525 550 550 600 575 650 625 500
