Twotailed test alpha 006 z0 188 z0 188 z 188 z0 2575z0

Two-tailed test, alpha = 0.06 -z0 = -188, z0 = 1.88; z 1.88 -z0 = -2.575,z0 = -2.575,z > 2.575 -z0 = -1.96, z0 = 1.96; z 1.96 -z0 = -2.33, z0 = 2.33; z 2.33 Test the claim about the population mean mu at the level of significance a. Assume the population is normally distributed. claim mu 35; alpha = 0.05; sigma = 2.7 sample statistics: x = 34.1, n = 35 Fail to reject Ho. There is not enough evidence at the 5% level of significance to support the claim. Reject Ho. There is enough evidence at the 5% level of significance to support the claim. Not enough information to decide. ANSWER. Write the word or phrase that best completes each statement or answers the

Solution

26) test statistic = ( 35 - 34.1 ) / ( 2.7 / sqrt ( 35) ) =  1.972027...
p-value = 0.0486066...
which is less than 0.05..
so, B ) reject H0.There is enough evidence to support at 5% level of significance!.....
