The daily wages (in ₹) of 15 workers in a factory are given below : 195, 185, 145, 155, 135, 180, 175, 200, 150, 125, 190, 180, 170, 175, 190 Find the mean daily wage.

Following figures relate the weekly wages (in Rs.) of 15 workers in a factory: 300,250,200,250,200,150,350,200,250,200,150,300,150,200,250 Prepare a frequency table. What is the range in wages (in Rs.) How many workers are getting Rs. 350? How many workers are getting the minimum wages?

Following figures relate to the weekly wages (in Rs.) of 15 workers in a factory: 300,250,200,250,200,150,350,200,250,200,150,300,150,200,250 Prepare a frequency table. What is the range in wages (in Rs)? How many workers are getting Rs. 350? How many workers are getting the minimum wages?

Consider the following distribution of daily wages of 50 workers of a factory. Daily wages (in Rs).: 100-120 120-140 140-160 160-180 180-200 Number of workers: 12 14 8 6 10 F i nd the mean daily wages of the workers of the factory by using an appropriate method.

The heights (in cm) of the volley-ball players from team A and term B were recorded as : Team A : 180, 178, 176, 181, 190, 175, 187 Team B : 174, 175, 190, 179, 178, 185, 177 Which team had the greater average height ? Find the median of team A and team B.

The heights, to the nearest cm, of 30 men are given below: {:(159, 170, 174, 173, 175, 160, 161, 164, 163, 165), (164, 171, 162, 170, 177, 185, 181, 180, 175, 165), (186, 174, 168, 168, 176, 176, 165, 175, 167, 180):} Using class intervals 155 - 160, 160 - 165, ... draw up a grouped frequency distribution and use this to estimate the Arithmetic mean and standard deviation.

The following table gives the daily income of 50 workers of a factory: Daily income (in Rs): 100-120 120-140 140-160 160-180 180-200 Number of workers: 12 14 8 6 10 Find the mean, mode and median of the above data.

The following data gives the production of foodgrains (in thousand tonnes) for some years: Year , 1995, 1996, 1997, 1998, 1999, 2000 Production (in Thousand tonnes), 120, 150, 140, 180, 170, 190 Represent the above data with the help of a bar graph.

The following table shows the distribution of the heights of a group of factory workers : Determine the cumulative frequencies {:(" Ht. (cm): ", 150- 155, 155-160, 160-165, 165-170, 170-175, 175-180, 180-185),(" No. of workers " ," "6, " "12, " "18, " "20, " "13, " "8, " "6):}

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
