Problem 3 Suppose that you have a set of n large, orderable, objects, each of size q, so that it requires time e(a) to time to compute a hash function h(a) for any object and requires time e(g) to compare any two objects. Describe a compound data structure, built out of a heap and a hash table, that supports the following operations with the specified run times.. elt (x) Is x an element of the set? Expected run time O(g)....

You
have a data set C1 and you do the following transformation using
statistical software: C2=C1/5
You find the mean, median and standard deviation of the
original C1 and the new C2 and compare them.
You must then answer the question pictured below. I assumed
"none of them" would be the answer since all three values changed
after the transformation, but that answer if wrong.

Create a simulated bivariate data set consisting of n 100 (xi, yi) pairs: Generate n random a-coordinates c from N(0, 1) Generate n random errors, e, from N(0, o), using o 4. Set yiBoB1x; + , Where Bo = 2, B1 = 3, and eN(0, 4). (That is, y is a linear function of , plus some random noise.) (Now we have simulated data. We'll pretend that we don't know the true y-intercept Bo 2, the true slope...

Suppose you are planning to collect a set of data in an experiment where the null hypothesis states that the population mean will be 15. You plan to collect 30 observations, and you expect the population standard deviation to be 6.5. Use the Statistical Applet: P-value of a Test of Significance to calculate the P-value for your final test of significance, considering the possibilities that your sample mean comes out to 12, 13, or 14, and considering the two possible...

= You run a regression analysis on a bivariate set of data (n 90). With t = 32.8 and y 56.2, you obtain the regression equation y = 3.482x + 43.485 with a correlation coefficient of r = 0.089. You want to predict what value (on average) for the response variable will be obtained from a value of 100 as the explanatory variable. You find that the regression equation p value is above your a value. What is the appropriate...
