The P-value is _____________________. (Round to three decimal places as needed.)

Based on the P-value, there is or is not sufficient evidence at a significance level of 0.05 to support or warrent rejection of the claim that the smokers have a mean continine level greater than the level of 2.84 ng/mL found for nonsmokers.

The claim is that smokers have a mean cotinine level greater than the level of 2.84 ng/mL found for nonsmokers. (Cotinine is used as a biomarker for exposure to
nicotine.) The sample size is n = 920 and the test statistic is t= 56.224. Use technology to find the P-value. Based on the result, what is the final conclusion? Use a
significance level of 0.05.
State the null and alternative hypotheses.
H₂H = 2.84
H₁: > 2.84
(Type integers or decimals. Do not round.)
The test statistic is

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
