Answer: 0.2551
Step-by-step explanation:
Given : The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean μ, the actual temperature of the medium, and standard deviation σ.
Significance level :
The critical z-value for 95% confidence : (1)
Since , (where x be any random variable that represents the temperature reading from a thermocouple.)
Then, from (1)
(2)
Also, all readings are within 0.5° of μ,
i.e.
i.e. [From (2)]
i.e.
i.e.
The required standard deviation :
Answer: 0.0668
Step-by-step explanation:
Given: Mean :
Standard deviation :
The formula to calculate z-score is given by :_
For x= 4 minutes , we have
The P-value =
Hence, the probability that on a given run, the time will be 4 minutes or less = 0.0668
