The normal distribution is called as standard normal distribution when Option 1: Mean () = 1 and standard deviation () = 0 for a data set Option 2: Mean () = 1 and standard deviation () = 1 for a data set Option 3: Mean () = 0 and standard deviation () = 1 for a data set Option 4: Mean () = 0 and standard deviation () = 0 for a data set

The answer is 'Mean () = 0 and standard deviation () = 1 for a data set'. View full solution:

The normal distribution is cal<=d as standard normal distribution when

Mean () = 0 and standard deviation () = 1 for a data set

Mean () = 1 and standard deviation () = 0 for a data set

Mean () = 1 and standard deviation () = 1 for a data set

Mean () = 0 and standard deviation () = 1 for a data set

Mean () = 0 and standard deviation () = 0 for a data set

Statistics & Applications

Easy

applied

Mean ( $\mu$ ) = 1 and standard deviation ( $\sigma$ ) = 0 for a data set

Mean ( $\mu$ ) = 1 and standard deviation ( $\sigma$ ) = 1 for a data set

Mean ( $\mu$ ) = 0 and standard deviation ( $\sigma$ ) = 1 for a data set

Mean ( $\mu$ ) = 0 and standard deviation ( $\sigma$ ) = 0 for a data set
