Not looking for the answer, I've just got myself confused. The scenario I have is: I have been given the Standard deviation figure 14.62 (years), normal distribution, n=26, 32% of 26 (n) are aged less than 50. What is the mean? (i.e I don't have z or the mean)

I've initially tried to 'back engineer' a standard calculation example I had to find the proportion of n below 50 with a mean of 53.4, Standard Deviation 14.2, but it didn't seem on track. Then tried to make sence of calculating z with Tables of the Normal Distribution, but I'm missing something, and just can't get me head around it now.

Regards,

Ade
