thank you

Rounding rules: z-value: round nearest hundredth. (e.g. 0.135 would enter as 0.14) t-value/chi-square value". round nearest thousandth. ((9.3. 1.2358 would enter as 1.236) p~va|uez round nearest ten'thousandth. (e.g. 0.13589 would enter as 0.1359) standard deviation: Round nearest thousandth. (e.g. 1.2358 would enter as 1.236) If your answer is then input as +/-. (eg. 1.25 would enter as +/-1.25) :> Question 1 5 pts A manager wishes to determine the relationship between the number of years her sales representatives have been employed by the rm and their amount of sales (in thousands of dollars) per month.
