The lengths of songs on the radio are normally distributed with a mean length of 210 seconds. If 38.2% of all songs have lengths
between 194 and 226 seconds, then the standard deviation of this distribution is: A) 16 seconds
B) 8 seconds
C) 32 seconds
D) 64 seconds
I’m suppose to construct a bell diagram for this question but don’t know how to without the standard deviation..... thx
Given that the lengths of songs on the radio are normally distributed with a mean length of 210 seconds, then the probability that a randomly selected <span>song will have length between 194 and 226 seconds is given by:
</span> <span> Given that the probability that </span><span>all songs have lengths between 194 and 226 seconds is 38.2% = 0.382, then
</span> <span> Therefore, the standard deviation of the distribution is 32 seconds.</span>
