Will give 100 will also mark brainliest !
the two dot plots below compare the forearm lengths of two groups of schoolchildren:

based on visual inspection of the dot plots, which group appears to have the longer average forearm length?

group b, because three children in the group have the least forearm length of 11 inches
group a, because three children in the group have the least forearm length of 11 inches
group a, because seven children have a forearm length longer than 12 inches
group b, because two children have a forearm length longer than 12 inches

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.
