14. The temperature of the water in the boiler is raising at the constant rate. The recordings taken every 115 minutes are as follows: 25 °C, 28 °C, 31 °C and so on. The last reading taken was 1.C. How many readings were taken in all? (Tn = ?) solve it

Asimple random sample of size nequals14 is drawn from a population that is normally distributed. the sample mean is found to be x overbar equals 70 and the sample standard deviation is found to be sequals13. construct a 90% confidence interval about the population mean

Polynomial that can be factored as (3x-4)(3x+4)
