- I need help on filling out this following table for statistics. Please help me find the chi squared value as well It has been suggusted that the highest priority of retirees is travel. Thus, a study was conducted to investigate the differences in the length of stay of a trip for pre- and post-retirees. A sample of 714 travelers were asked how long they stayed on a typical trip. The observed results of the study are found below. You may round all answers for this problem to the nearest hundredth. To import data to R, copy and paste the R codes below number=c(rep("4-7",421),rep("8-13",154),rep("14-21",88),rep("22_or_more",51)) retirement=c(rep("pre-retirement",248),rep("post-retirement",173),rep("pre-retirement",79),rep("post-retirement",75),rep("pre-retirement",36),rep("post- retirement",52),rep("pre-retirement",11),rep("post-retirement",40)) data=data.frame(number,retirement) table(data) With this information, construct a table of estimated expected values.

The technique is very similar to the one used with the Feynman-Kac formula back in MATH 467. Let's consider the PDE given by with terminal condition f(T,x) af + Ət 1 02 ર .2მ2 f af მ2 +rx მე - rf = 0, = (x-K)+. The solution f(t, x) corresponds to the price of a call option (given the initial condition) at time t if the stock price is x. (a) The first two things that prevent us from solving this PDE directly are (i) the fact that we have a terminal condition, instead of an initial condition; (ii) the terms in front of the derivatives are not constant. To address these, we use the transformation g(t, x) = ƒ(T − t,e³), equivalent to f(t, x) = g(T-t, log(x)). Under this condition, determine the PDE and the initial condition satisfied by g. (b) Now, the PDE obtained in (a) should have an initial condition and constant coeffi- cients, but it still…arrow_forwardPlease help me answer question b and c for this problem.A student project involved collecting data to see if there was a difference in the amount of time one had to wait at the drive-thru between two fast food restaurants, A and B.

- Please help me with the following statistics problem A long-distance runner wants to compare the durability of two running shoe brands: Brand A and Brand B. Instead of testing them separately, 15 runners simultaneously wear Brand A on the left foot and Brand B on the right foot during training runs. The runner continues training as usual and tracks how many kilometers each shoe lasts before showing significant wear (e.g., loss of cushioning, outsole damage). Since both shoes experience the same runner, terrain, and conditions, any lifespan difference can be attributed to the shoe brand rather than external factors. Test whether Brand A running shoes have a significantly shorter lifespan than Brand B when worn under the same conditions by the same runner.

A code of 0 indicates the person does not have a gambling problem, a code of 1 indicates the person does have a gambling problem. The data is found in the accompanying data file. Download.csv file To count the frequencies of 0 and 1 in each sample, use the table(your_dataset_name$ column's name) function.

(a) Determine the price Fo of this option at time t = : 0 (today). (b) Using the formulas provided in the lecture videos, calculate the value of each of the Greeks for this option.

Five resistors are randomly selected from this box without replacement (oncemoved from the box it is not returned to the box), what is the probability that oneor more of the defective resistors is among those selected? b. Five resistors are randomly selected from this box with replacement (after theresistor is removed and checked, it is returned to the box prior to the nextselection (hence the same resistor can be selected more than once)), what is theprobability that one or more of the defective resistors is among those selected?arrow_forwardBusiness Discussarrow_forwardTriola statistics Readers who prefer printed books Readers who prefer e-booksarrow_forward
