A manufacturing company produces electric insulators. You define the variable of interest as the strength of the insulators. If the insulators break when in use, a short circuit is likely. To test the strength of the insulators, you carry out destructive testing to determine how much force is required to break the insulators. You measure force by observing how many pounds are applied to the insulator before it breaks. You collect the force data for 30 insulators selected for the experiment and find out that the mean force is 1670. The population mean force that you try to estimate is_______.
a. a confidence interval.
b. a statistic.
c. a point estimate.
d. a parameter.
e. an interval estimate.
Answer:
b. a statistic.
Step-by-step explanation:
the value 1670 is regarded as a statistic. this is because it is a representation of the value of a sample. from the question we get that destructive testing is being done this shows is that what we have here is a sample.
the mean force 1670 is not a parameter, a point estimate, a confidence interval or interval estimate. therefore option b is the answer.

__________ refers to the degree of correlation among independent variables in a regression model. a. Multicollinearity b. Tolerance c. Rank d. Confidence level
Answer:
Option A: Multicollinearity
Step-by-step explanation:
Multicollinearity is said to be present when there are high correlations between two or more independent variables called predictor variables. In simple terms, Multicollinearity refers to when the independent variables present in a regression model are correlated.
Tolerance is simply used to detect Multicollinearity.
Rank is basically the model in which the ranks of the dependent variable are said to have regressed on a set of characteristics in the experiment known as covariates.
Confidence level is the percentage of all possible samples that we can expect to be included within the true population parameter.
Looking at all the definitions, the one that fits with the statement in the question is Multicollinearity.

Total solar eclipses occur on a regular and predictable basis. One that could be viewed in parts of the United States occurred on March 7, 1970. The saros cycle is a period of 18 years, 11 1 3 days, and solar eclipses occur according to this cycle. For the purposes of this exercise, we ignore leap years and assume that a year is exactly 365 days. Because the saros cycle is not a whole number of days, but instead is one-third of a day longer than a day, at the end of the saros cycle, Earth will have rotated one-third revolution beyond its location at the beginning of the cycle. Thus, if a solar eclipse is viewable at a certain location, the next solar eclipse will not be. How long after March 7, 1970, will a solar eclipse again be viewable from the United States?
Answer:
Step-by-step explanation:
The previous solar eclipse occured on March 7 , 1970 .
saros cycle has duration of 18 years , 11 + 1/3 days
So the earth goes 1 / 3 of its daily rotation beyond its previous location in the next solar eclipse on the earth . In order that we get solar eclipse on the same point on the earth , we shall have to wait for third solar eclipse
So total period of wait = 18 x 3 years + 11 x 3 + 1 = 54 years and 34 days
Date of next solar eclipse on the same spot = 1970 + 54 = 2024
7 th March + 34 days = April 10
likely date = April 10 , 2024 .

An electronics company has a contract to deliver 21,475 radios within the next four weeks. The clientis willing to pay $20 for each radio delivered by the end of the first week, $18 for those delivered by theend of the second week, $16 by the end of the third week, and $14 by the end of the fourth week. Sinceeach worker can assemble only 50 radios per week, the company cannot meet the order with its presentlabor force of 40; hence it must hire and train temporary help. Any of the experienced workers can betaken off the assembly line to instruct a class of three trainees; after one week of instruction, each of the trainees can either proceed to the assembly line or instruct additional new classes.
At present, the company has no other contracts; hence some workers may become idle once the delivery is completed. All of them, whether permanent or temporary, must be kept on the payroll 'til the end of the fourth week. The weekly wages of a worker, whether assembling, instructing, or being idle, are $200; the weekly wages of a trainee are $100. The production costs, excluding the worker's wages, are $5 per radio. The company's aim is to maximize the total net profit.
Required:
Formulate this as an LP problem (not necessarily in the standard form).
Step-by-step explanation:
See attached a detailed annotation of the LP formulation
let is describe the problem bellow.
An electronics company has a contract to deliver 21,475 radios within
the next four weeks. The client is willing to pay
$20 for each radio delivered by the end of week 1
$18 for each radio delivered by the end of week 2
$16 for each radio delivered by the end of week 3
$14 for each radio delivered by the end of week 4
Each worker can assemble 50 radios/wk.
Size of present workforce = 40.
Any experienced worker can be taken off the assembly line to instruct a class
of three trainees; after one week of instruction, each of the trainees can
either proceed to the assembly line or instruct additional new classes.
Weekly wages for experienced workers: $200
Weekly wages for trainees: $100
Production costs, excluding wages: $5/radio.
