Acircle has a circumference of 59 cm

using 3.14 as an approximation for π, what is the approximate value for the radius of of the circle

a 4.7 cm
b 9.4 cm
c 18.8 cm
d 37.6 cm

If you measured the width of a window in inches and then in feet with measurement would you have the greater number of units

Need solving this 2nd limit problem.

The null and alternate hypotheses are: h0: μ1 ≤ μ2 h1: μ1 > μ2 a random sample of 22 items from the first population showed a mean of 113 and a standard deviation of 12. a sample of 16 items for the second population showed a mean of 99 and a standard deviation of 6. use the 0.01 significant level. find the degrees of freedom for unequal variance test. (round down your answer to the nearest whole number.) state the decision rule for 0.010 significance level. (round your answer to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? use the 0.01 significance level.
