The heights of 82 roller coasters have a mean of 280.7 feet and a population standard deviation of 59.3 feet. Find the standardi
zed tests statistics and the corresponding p-value when the claim is that roller coasters are less than 290 feet tall. Group of answer choices
a. z-test statistic = -0.78, p-value = 0.2181
b. z-test statistic = 0.78, p-value = 0.2181
c. z-test statistic = 0.78, p-value = 0.4361
d. -test statistic = -0.78, p-value = 0.4361
