To find the mean of a number sequence, add all the numbers together and divide them by the number of numbers used...

10 + 11 + 10 + 10 + 8 = 49

49 ÷ 5 = 9.8

The mean does not match 10, so make up numbers untill it matches.

10 + 11 + 10 + 10 + 8 + 6 ÷ 6

= 10 !

The anwser would be y = 6

bulgar [2K]

Answer:

0.1

Step-by-step explanation:

Solving using empirical rule formula

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

Hence, the lower bound 95% =

μ - 2σ

Mean = 0.2

Standard deviation of 0.05

= μ - 2σ

= 0.2 - 2(0.05)

= 0.2 - 0.1

= 0.1

The lower bound is 0.1
