The following table gives the life times of 400 neon lamps:
Life time (in hours) | Number of lamps |
300 - 400 400 - 500 500 - 600 600 - 700 700 – 800 800 – 900 900 - 1000 | 14 56 60 86 74 62 48 |
(i) Represent the given information with the help of a histogram.
(ii) How many lamps have a life time of more than 700 hours?
The parts of the questions are solved below:
(i) The above given information is represented with the help of histogram below:
(ii) 74 + 62 + 48 = 184
Hence, 184 lamps have a life time of more than 700 hours.
