Question: ECONOMIC SURVEYS A survey of the opinions of 10 leading economists in a certain country showed that, because oil prices were expected to drop in that country over the next 12 months, 7 had lowered their estimate of the consumer inflation rate. 8 had raised their estimate of the gross national product (GNP) growth rate. 2 had lowered their estimate of the consumer inflation rate but had aised their estimate of the GNP growth rate. How many economists had both lowered their estimate of the consumer inflation rate and raised their estimate of the GNP growth rate for that period?
