Х According to a Nielsen survey, radio reaches 88% of children each week. Suppose we took weekly random
samples of n = 125 children from this population and computed the proportion of children in each sample
whom radio reaches.
What will be the shape of the sampling distribution of the proportions of children the radio reaches?

Choose 1

A. Skewed to the left
B. Skewed to the right
C. Approximately normal
D. Uniform

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.
