A random sample of 100 former computer science students from Arthur Jarvis University showed an
average income of N10,000,000 after three years of graduating with a sample estimate of the standard
deviation equal to N500,000. Assume that students income are normally distributed, Construct a 95%
confidence interval for the mean income of all computer science graduates from AJU
 
Please show us that you have anything to offer. Do you kow what a Confidence Interval looks like? Have you ever seen one constructed? Show YOUR work, please.

I haven't seen one constructed and do not know what it looks like.
 
Mean - Some Number of Standard Deviations
Mean + Some Number of Standard Deviations

"Some Number" is determined by the confidence selection, in this case 95%.
