A standard survey is a common type of survey that provides a methodological or operational survey framework.
seven successive tasks of a standard survey are
1. Off-site preparation:- Some preparation done before going to field visits like the selection of area, resident, etc.
2. Entrance conference:- It is basically done for taking permission for the survey and the knowledge of participants about the survey which encourages participation.
3. Initial tour:- In the initial tour surveyors start the observation of some samples which helps in the later stage.
4. Resident sample selection:- During this stage the surveyors choose some resident sample in a method called case mixed stratified method. The sample selection in this stage is based on the selection from the initial tour.
5. Information gathering:- In this stage, the actual data and information are gathered.
6. Information analysis and deficiency determination:- In this stage, the surveyors analyze the data and identify the deficiencies.
7. Exit conference:- This is the last stage in which the surveyors present the findings to the officials.
How does a professional helper implement the seven tasks in a human service intervention?
1. Let X, X, and X represent the times necessary to perform successive repair tasks at a certain service facility. Suppose they are independent, normal random variables with expected values p4-14 t4-60 and ?_?? ?? 15. Consider the probability a. (10 pts. 2+ 3+2+3). Is the random variable T- X5 X2-.5x, normal? Why? Calculate its expectation and variance. DAT b. (6 pts.) Calculate the desired probability.
The table below lists the results of a survey which explored the food expenditures of seven families. The survey was developed to determine if there was a correlation between monthly income and food expenditure. Which variable is the dependent variable? Monthly Income ($) Food Expenditure ($) 2300 100 2800 950 3700 1400 4500 1500 2100 900 3200 1300 3000 1100 Multiple Choice Monthly income The seven families Food expenditure There is no dependent variable
2. Let Xi, X2, and X represent the times necessary to perform three successive repair tasks at a certain service facility. Suppose they are independent normal random variables with expected values μι μ2, and ,13 and variances σ σ and σ3 respectively. a. If,-μ2-13-65 and ol-02-03-20, calculate P(Xi + X2 +X3 210). What is P(150 sXX23210)? Using the μ's and σ's given in part (a), calculate POX259)and P(62 SX568) Using the μ's and ơi's given inpart (a), calculate P(-10 Xi-5X2-5X3...

A survey is taken on average commute time to work. The mean and standard deviation of the survey are as follows: Mean commute time: 30 minutes Standard deviation: 10 minutes 14. Use the mean and standard deviation above to calculate the z-score of a 45 minute commute to work. Explain what this z-score tells us.

Let X = the time between two successive arrivals at the drive-up window of a local bank. If X has an exponential distribution with λ= 1, (which is identical to a standard gamma distribution with α = 1), compute the following. (If necessary, round your answer to three decimal places.) (a) The expected time between two successive arrivals (b) The standard deviation of the time between successive arrivals (c) P(X ≤ 2) (d) P(3 ≤ X ≤ 5)
