The duration of Muž z neznáma is 1.33 hours.
z = (x-mu)/sigma So x = sigma*z + mu = 3m*(-3) + 25 = -9m + 25
Z = (x minus mu) divided by sigma.
The duration of Liza with a Z is 3060.0 seconds.
The duration of Roujin Z is 1.33 hours.
The duration of Z-Cars is 1500.0 seconds.
If a score ( s ) is equal to the mean of a dataset, its z-score will be 0. The z-score is calculated using the formula ( z = \frac{s - \mu}{\sigma} ), where ( \mu ) is the mean and ( \sigma ) is the standard deviation. Since ( s ) equals ( \mu ), the numerator becomes zero, resulting in a z-score of 0. This indicates that the score is exactly at the average of the dataset.
Denote by mu the mean of X. Given P(X>5.52)=0.305 i.e., P((X-mu)/4> (5.52-mu)/4)=0.305 So, letting Z=(X-mu)/4. Then Z~N(0,1). Hence, the above equality is P(Z>(5.52-mu)/4)=0.305. So, (5.52-mu)/4=0.51 So, mu=5.52-4*0.51=3.48 So, the best answer is 3.5
