?

is some place in the scope of 48 and 52? ?

?

c. If a 10 mL test is taken out, what is the probability that the typical number per mL ?

?

of particles in the eliminated model is some place in the scope of 48 and 52? ?

?

d. How gigantic a model ought to be taken out with the objective that the ordinary number of particles per mL in ?

?

the model is some place in the scope of 48 and 52 with probability 95%? ?

?

In a self-assertive illustration of 100 batteries made by a particular procedure, the typical ?

?

lifetime was 150 hours and the standard deviation was 25 hours. ?

?

level of conviction can this statement is made? ?

?

(iv) Approximately the quantity of batteries ought to be examined with the objective that a 95% assurance ?

?

stretch will demonstrate the expect to inside 2 hours? ?

?

?

stretch will decide the plan to inside 2 hours ?

?

A Company researcher has been given the task of social affair information practically all agents ?

?

inside the association to all the more promptly appreciate the sufficiency of their high level training pathway ?

?

program offered to all delegates. The probability that a specialist has been at the association ?

?

at any rate five years is 0.74, the probability that a delegate has a Master's level testament or ?

?

higher is 0.34, and the probability that a subjectively picked specialist has been at the association ?

?

at any rate five years and has a Master's authentication is 0.12. ?

?

F. Of the people who have an advanced education 35.29% have been at the association at any rate 5 years ?

?

while those with lower degrees 93.94 % have been at the association at any rate 5 years. Make a probability tree depicting the current condition. ?

?

(iii) A planner ensures that the mean lifetime is some place in the scope of 147 and 153 hours. With what ?

?

level of assurance can this affirmation is made? ?

?

(iv) Approximately the quantity of batteries ought to be tried with the objective that a 95% conviction ?

?

length will decide the expect to inside 2 hours? ?

?

(v) Approximately the quantity of batteries ought to be tried with the objective that a 99% conviction ?

length will decide the plan to inside 2 hours??

Question 3: Assume that a ISE student gets "grade A" from his courses with probability 1/4 (independent of the grade he gets from other courses). Suppose that s/he takes only two courses on a given semester ( Decision Theory and Quality Control) , what is the probability that he gets "grade A" from those two courses given that; a) He has got an "grade A" from Quality Control, b) He has got at least one grade A?d. Do the sample standard deviations target the value of the population standard deviation? In general, do sample standard deviations make good estimators of population standard deviations? Why or why not? OA. The sample standard deviations do target the population standard deviation, therefore, sample standard deviations are unbiased estimators. OB. The sample standard deviations do target the population standard deviation, therefore, sample standard deviations are biased estimators. Oc. The sample standard deviations do not target the population standard deviation, therefore, sample standard deviations are biased estimators. OD. The sample standard deviations do not target the population standard deviation, therefore, sample standard deviations are unbiased estimators.You calculated the standard deviation of a data set assuming that the data were from a population standard deviation. You later nd that the data were from a sample. Using the same data, vou calculate the standard deviation for the sample. What is the relationship between the population standard deviation and the sample deviation and the sample standard deviatiot? Select one AI he population standard deviation is less than the sample standard deviation B. The population standard deviation is greater than the sample standard deviation Cfou cannot determine the relationship between the population standard deviation and the sample standard deviation D.The population standard deviation is equal to the sample standard deviation Question: For the same frequency distribution shown in the above problem, the standard deviation for the number of subscriptions per household is approximately: (a) Standard Deviation = 1.2 (b) Standard Deviation = 1.5 (c) Standard Deviation = 1.8 (d) Standard Deviation = 2.0 (e) Standard Deviation = 2.3 (f) Standard Deviation = 3.0 (g) None of the above
