Which measure of central tendency is not affected by extremely high or low scores in a dataset?

he time to failure (in days) of a starter motor in a vehicle is modeled as a Weibull distribution with δ = 4000, β = 2.4.  What is the probability that a starter motor fails within 4 years?  (Assume that there are 365 days in a year).  

Which graphical representation is specifically suited for illustrating frequency distributions of qualitative variables?

What defines a confounding variable in a study?

Your exercise routine requires you to travel to the gym, complete your workout, and return home. Suppose that the proportion of the total time for travel to the time at the gym follows a beta distribution with α = 0.5 and β =1.   What is the probability that the proportion of time for travel to the gym exceeds 0.68?

How would you combine two vectors `a` and `b` as columns in R?

The random variable X has probability distribution. x 1 3 5 7 9 P(X=x) 0.2 p 0.2 q 0.15   Given that E(X) = 4.5, find the values of p and q.

The number of flaws in bolts of cloth in textile manufacturing is assumed to be Poisson distributed with a mean of 0.1 flaw per square meter. What is the probability that there are two flaws in 10 square meters of cloth?

How does the concept of relative frequencies enhance the interpretability of frequency distributions?

What distinguishes a cumulative relative frequency distribution from a cumulative frequency distribution?
