Question

A hypothesis test is conducted with H0:μ=55H0:μ=55 and H1:μ<55H1:μ<55. A simple random sample of size n=47n=47 is drawn, and ¯x=49x¯=49. The population standard deviaiton is σ=20σ=20.

Compute the test statistic. (Round to two decimal places.)

Determine the P-value. (Round to four decimals places.)
