Ocean currents act as conveyor belts of warm and cold water,

sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. ... The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
Answer:
The correct option is;
D. This method uses the binomial probability distribution with the P-value method ans uses the value of p assumed in the null hypothesis
Step-by-step explanation:
Here we have the binomial probability distribution is used to test claims about a proportion then the requirement is np > 5 and nq >5
In a left-tailed test, the P value is the probability of getting x or fewer successes among n trials while in a right tailed test, the P-value is the probability of getting x or more successes among n trials
However, the P-value where a binomial distribution is used to test a claim about a proportion is derived from the z score of the parameters of the statistic and not from the p assumed in the null hypothesis.
