Question

ldentify the test statistic (Round to two decimal places as needed.) ldentity the P-value. The P-value is(Round to throe doornal places as needed ) Choose the correct answer below A. Fa to reject Ho There is rsufficient evidence to condude that the population of eamaates has mean mapetude greater than too O B. Reject Ho. There is insufficient evidence to conclude that the population of earthquakes has a mean magnitude greater than 1.00 O C. Falil to reject Ho There is sufficient evidence to conclude that the population of earthquakes has a mean magnitude greater than 1.00 D. Reject Ho- There is sufficient evidence to condlude that the population of earthquakes has a mean magnitude greater than 1.00

Explanation / Answer

For the data given:

Sample mean, m = 1.1832

Sample SD, S = 0.587

Sample size, n = 50

Calculating test statistic:

t = (m-1)/(S/n0.5) = (1.1832-1)/(0.587/500.5) = 2.206

The corresponding p-value is: 0.016

You have not mentioned the significance level for this test, so I assume it to be 0.05

Since p < 0.05, so reject the null hypothesis. There is sufficient evidence to conclude that the population has mean greater than 1.

Hope this helps !
