Following are the wages of 8 workers in rupees: `50, 62, 40, 70, 45, 56, 32, 45` If one of the workers is selected at random, what is the probability that his wage would belower than the average wage?

Consider the following data: What is the variability in the wages of the workers in Factory - A?

Given below is the frequency distribution of wages (in Rs.) of 30 workers in a certain factory: Wages (In Rs. 110-130 130-150 150-170 170-190 190-210 210-230 230-250 No. of workers 3 4 5 6 5 4 3 A worker is selected at random. Find the probability that his wages are: less than Rs. 150 (ii) at least Rs. 210 more than or equal to 150 but less than Rs. 210

Given below is the frequency distribution of wages (in Rs.) of 30 workers in a certain factory: Wages (in Rs.) 110-130 130-150 150-170 170-190 190-210 210-230 230-250 No. of workers 3 4 5 6 5 4 3 A worker is selected at random. Find the probability that his wages are: (i) less than Rs. 150 (ii) at least Rs. 210 (iii) more than or equal to 150 but less than Rs. 210.

In factory, the daily wages (in Rs.) of 12 works are 75, 90 100, 120, 110, 114, 50, 60, 70, 105, 108, and 102. find the number of workers whose daily wage is less than the mean daily wage.

Given below is the frequency distribution of wages (in Rs.) of 30 workers in a certain factory: {:("Wages (In Rs.)", 110-130,130-150,150-170,170-190,190-210,210-230,230-250),(" No. of workers", ""3,"4","5","6","5","4","3"):} A worker is selected at random. Find the probability that his wages are: (i)less than Rs. 150 (ii) at least Rs. 210 (iii)more than or equal to 150 but less than Rs. 210

Following are the wages of 19 workers: {:("Wages(Rs.)",10,20,30,40,50),("Number of Workers",4,5,3,2,5):} Calculate arithmetic mean, using Short-cut Method.

Given below is the frequency distribution of wages: A worker is selected at random. Find the probability that his wages are: (i) less than Rs. 150 (ii) at least Rs. 210 (iii) more than or equal to 150 but less than Rs. 210.

Total daily wages of the workers in a factory is 3150 rupees. If the number of workers is decreased by '.5' and the wages of the remaining is increased by 5 then the total. wages become 3250 rupees. What is the wages of a worker?
