step-by-step explanation:

b. 134

Step-by-step explanation:

Given : A minimum usual value of 135.8 and a maximum usual value of 155.9.

Let x denotes a usual value.

i.e. 135.8< x < 155.9

Therefore , the interval for the usual values is [135.8, 155.9] .

If interval for any usual value is [135.8, 155.9] , then any value should lie in this otherwise we call it unusual.

Let's check all options

a. 137 ,

since 135.8< 137 < 155.9

So , it is usual.

b. 134

since 134<135.8 (Minimum value)

So , it is unusual.

c. 146

since 135.8< 146 < 155.9

So , it is usual.

d. 155

since 135.8< 1155 < 155.9

So , it is usual.

Hence, the correct answer is b. 134 .
