- which option is correct The data mining term of "score" is known as a(n) _______________ in statistical terminology. Multiple Choice forecast record algorithm featurePeople are classified as hypertensive if their systolic blood pressure (SBP) is higher than a specified level for their age group, according to the algorithm in the table below. Assume SBP is normally distributed with mean, and standard given in the table for age groups 1 – 14 and 15 – 44, respectively. Define a family as a group of two people in age group 1 – 14 and two people in age group 15 – 44. A family is classified as hypertensive if at least one adult and at least one child are hypertensive. i. What proportion of 1 – 14-year-olds are hypertensive? ii.

Because the number of slotsremains relatively stable, some colleges reject more early applicants. Suppose thatfor a recent admissions class, an Ivy League college received 2851 applications forearly admission. Of this group, it admitted 1033 students early, rejected 854outright, and deferred 964 to the regular admission pool for further consideration.In the past, this school has admitted 18% of the deferred early admission applicantsduring the regular admission process. Counting the students admitted early andthe students admitted during the regular admission process, the total class sizewas 2375. Let ?, ?, and ? represent the events that a student who applies for earlyadmission is admitted early, rejected outright, or deferred to the regularadmissions pool.a. Are events E and D mutually exclusive? Find (? ∩ ?)b. Suppose a student applies for early admission. What…5 What is the K-means clustering method?
- Google is testing 3 different search algorithms, A, B, and C. Ideally, a good algorithm would show the user a link they want to click on right away. An algorithm where the user needs to try many searches before they find something they want is not as good. One way Google judges a search algorithm is to see how many searches a user does until the user clicks on a link. The fewer the searches, the better the algorithm. After collecting sample data from random users running the three algorithms, Google conducts an ANOVA (analysis of variance) test for the mean number of searches before clicking on a link. Suppose the p-value is 0.024. (a) Write the null and hypotheses. Define all parameters. (b) Write the conclusion verbally and in context.you are asked to create a stemplot for a collection of four digit pieces of data: 6574, 2089, 8891, 6452, 1446, 7799.
