Question

If daily wages of 5 workers in a factory are 45, 32, 59, 37 and 52, then Mean of this data is __________ .(a) 45
(b) 32
(c) 31
(d) 63

Answer 1

Answer:

(a) 45

Step-by-step explanation:

Mean = Summation of data / No. of data.

Hence

Mean = (45+32+59+37+52)/5

= 225/5

= 45

Answer 2

Answer:

Mean of given data = 45

Option A is correct.

Step-by-step explanation:

Mean of ungrouped data is given by

$\boxed{\bar x = \frac{sum \: of \: all \: observation}{total \: number \: of \: observation}}$

here in the given question,

Total observation = 5

Value:45, 32, 59, 37 and 52

$mean = \frac{45 +32 + 59 +37 + 52 }{5} \\ \\ = \frac{225}{5} \\ \\ = 45$

Hence, option a is correct.

Hope it helps you.
