Suppose that 14 children, who were learning to ride two-wheel bikes, were surveyed to determine how long they had to use training wheels. It was revealed that they used them an average of eleven months with a sample standard deviation of two months. Assume that the underlying population distribution is normal. Part (a) (i) Enter an exact number as an integer, fraction, or decimal. x = (ii) Enter an exact number as an integer, fraction, or decimal. sx = (iii) Enter an exact number as an integer, fraction, or decimal. n = (iv) Enter an exact number as an integer, fraction, or decimal. n − 1 = Part (b) Part (c) Part (d) Which distribution should you use for this problem? (Enter your answer in the form z or tdf where df is the degrees of freedom.) Explain your choice. Construct a 99% confidence interval for the population mean length of time using training wheels.
