I was hoping that someone can help to explain exactly what this means. I was able to do the problem but do not understand what the answer actually means. Thanks

mean is $39,395.69

~ is $20,023.69

had to find confidence intervals at 90, 95 and 99%

got CI is 90% is +/- $3,293.88 so TPM is $36,101.12 to $42,688.880

95% is +/- $3,924.51 so TPM is $35,470.49 to $43,319.51

99% is +/- $5,157.92 so TPM is $34,237.08 to $44,552.92

Can anyone please explain what these numbers mean, THANKS is advance :o)
