Question 40

The time, $T$ minutes, required for a specific bacterial culture to double in population is modelled by a normal distribution such that $\sim \text{N}(\mu, \sigma^2)$ .

Given that $P (T < 145) = 0.74$ , determine:

$P (T > 145)$

[1]

$P(μ<T<145)P(\mu < T < 145)$

[2]

$\mu \mid T < 145)$
