1. A fund-raising company solicits donations by telephone. It has been found that 60% of all calls result in a refusal to donate; 30% result in a request for more information through the mail, with a promise at least to consider donating; and 10% generate an immediate credit-card donation.

Do the data support the usual pattern of outcomes.
