Just realized. I'm already 14 now. I am terrible at math. Have I been chasing the wrong dream this entire time. It feels terrible to face the truth, but I'm just NOT GOOD AT MATH.

I've always been dreaming of making a salary with 6 digits. Now that it is nearly impossible for me to become an engineer, are there any other suggestions? Its gotten so bad, that I can't sleep anymore. :(

On the other hand, I've been told that I have talents in the following:

Music
Art
Impromptu Speech / Debate

Its too ambiguous! I need an expert opinion on my career path.

A recent article in the Wall Street Journal reported that the 30-year mortgage rate is now less than 6 percent. A sample of eight small banks in the Midwest revealed the following 30- year rates (in percent):

4.8 5.3 6.5 4.8 6.1 5.8 6.2 5.6
At the .01 significance level, can we conclude that the 30-year mortgage rate for small banks is less than 6 percent? Estimate the p-value.

Experience raising New Jersey Red chickens revealed the mean weight of the chickens at five months is 4.35 pounds. The weights follow the normal distribution. In an effort to increase their weight, a special additive is added to the chicken feed. The subsequent weights of a sample of five-month-old chickens were (in pounds):

4.41 4.37 4.33 4.35 4.30 4.39 4.36 4.38 4.40 4.39
At the .01 level, has the special additive increased the mean weight of the chickens? Estimate the p-value.
