The mean of a normally distributed set of data is 53 with a standard deviation of 6. Approximately 95% of all cases are expected to be between...

2 standard deviations of the mean. so, 41 to 65

Step-by-step explanation:

from the empirical rule we know that for 95% we are in 2 standard deviations of the mean. so:

53- 6- 6 = 41

*2 minus 6s because 2 standard dev. with the mean

53 + 6 + 6 = 65

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
