Table 6 shows the population, in thousands, of harbor seals in the Wadden Sea over the years 1997 to 2012. a. Let x represent time in years starting with x=0 for the year 1997. Let y represent the number of seals in thousands. Use logistic regression to fit a model to these data. b. Use the model to predict the seal population for the year 2020. c. To the nearest whole number, what is the limiting value of this model?
Q7. Many manufacturing companies in the United States and abroad use molded parts as components of a process. Shrinkage is often a major problem. Thus, a molded die for a part is built larger than nominal size to allow for part shrinkage. In an injection molding study it is known that the shrinkage is influenced by many factors, among which are the injection velocity in ft/sec and mold temperature in ◦C. The following two data sets show the results of a designed experiment in which injection velocity was held at two levels (low and high) and mold temperature was held constant at a low level. The shrinkage is measured in cm × 104. Shrinkage values at low injection velocity: 72.68, 72.62, 72.58, 72.48, 73.07, 72.55, 72.42, 72.84, 72.58, 72.92 Shrinkage values at high injection velocity: 71.62, 71.68, 71.74, 71.48, 71.55, 71.52, 71.71, 71.56, 71.70, 71.50(a) Construct a dot plot of both data sets on the same graph. Indicate on the plot both shrinkage means, that for low injection velocity…

With the growth of internet service providers, a researcher decides to examine whether there is a correlation between cost of internet service per month (rounded to the nearest peso) and degree of customer satisfaction (on a scale of 10 - 100 with a 10 being not at all satisfied and a 100 being extremely satisfied). The researcher only includes programs with comparable types of services. A sample of the data is provided below. d. Using your equation, estimate the satisfaction of the customer if the cost is P1175 per month. Ans = Blank 5 e. Using your equation, estimate the satisfaction of the customer if the cost is P245 per month. Ans = Blank 6
Your company manufactures plastic wrap for food storage. The tear resistance of the wrap, denoted by X, must be controlled so that the wrap can be torn off the roll without too much effort but it does not tear too easily when in use. In a series of tests (see data table below), 15 rolls of wrap are made under carefully controlled conditions and the tear resistance of each roll is measured. The results are used as the basis of a quality assurance specification. If X for a subsequently produced roll falls more than two standard deviations away from the test period average, the process is declared out of specification and production is suspended for routine maintenance.

The investment is expected to grow during the year by 10% with SD 35%. Assume a normal model for the change in value. (b) How much smaller would the annual SD of the investment need to become in order to reduce the VaR to $100,000? Assume that the expected growth remains 10%. (a) The value at risk (VaR) for an investment of $400,000 at 2% is _____ (Round to the nearest thousand dollars as needed.) (b) The annual SD of the investment would need to become _______%.

Researchers studied the effect of a houseplant fertilizer on carrot sprout growth. They randomly selected some carrot seeds to serve as controls, while others were planted in aluminum planters to which fertilizer sticks were added. Other conditions were held constant between the two groups. The following table shows data on the heights of plants (in cm) 2 weeks after germination. Use a t test to investigate whether the fertilizer has an effect on average carrot sprout growth. Use a = 0.05.

In Australia, wheat grain exports are often affected by little insects, it has been estimated that between one quarter and one third of the world grain crop is lost each year during storage and transportation. Even with the strictest safety precautions and protocols, these insects are not completely eliminated. At the start of the voyage, 40 ants remained among the wheat grains in the cargo hold of the ship. One week into the voyage, there were approximately 310 ants. The model used to estimate the number of ants, N, is N(t) = 400/1+9e(to the power of kt) a) a) although the question says there are 40 ants on the ship at the start of the trip, the exporters wanted independent algebraic proof using the proposed model of N(t)=400/1+9e(to the power of kt) show how the captain used the model to prove there were 40 ants initially N(0) 400/10 = 40 ants b) rearrange the model , without substitution of values , to K= K= In(1/9(400/n(t) -1 )) / 1 c) Now , find the value of k correct to 2…

We are interested in studying cigarette demand by young adults. Lets consider thefollowing model: ncaj = β0 + β1price + β2age + β3income + u a)Consider now an extension of the model that allow the effect of theprice to differ by age. Holding all other factors fixed, is the effect of price onncaj constant? (This part is theoretical and you do not have to estimate themodel.) b) Now consider the following model:ln(ncaj) = β0 + β1ln(price) + β2age + β3income + u Using the same sample above we have obtained the following results:ln\(ncaj) = 1.17− 0.69price + 0.06age + 0.009income Is there enough evidence to say that an increase of 1000 dollars in income,while keeping price and age fixed, increases cigarette consumption by lessthan 1%?
