Assume that each of your calls to a popular radio station has a probability of p = 0.04 of connecting, that is, of not obtaining a busy signal. Assume that your calls are independent.

(a) What is the probability that your first call that connects is your tenth call? Round your answer to four decimal places (e. g. 98.7654).

(b) What is the probability that it requires more than five calls for you to connect? Round your answer to four decimal places (e. g. 98.7654).

(c) What is the mean number of calls needed to connect? Round your answer to two decimal places (e. g. 98.76).

Which three lengths could be the lengths of the sides of a triangle? 21 cm, 7 cm, 7 cm 9 cm, 15 cm, 22 cm 13 cm, 5 cm, 18 cm 8 cm, 23 cm, 11 cm

If a line is defined by the equation y = 5x + 2, what is the slope?

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.
