Question
Consider the hypotheses shown below. Given that
x overbarxequals=5656,
sigmaequals=1111,
nequals=3737,
alphaequals=0.010.01,
complete parts a and b.
Upper H 0H0:
muless than or equals5454
Upper H 1H1:
mugreater than>5454
a. What conclusion should be drawn?
b. Determine the p-value for this test.
a. The z-test statistic is
nothing.
(Round to two decimal places as needed.)
The critical z-score(s) is(are)
nothing.
(Round to two decimal places as needed. Use a comma to separate answers as needed.)
Because the test statistic
is greater than the critical value,
is less than the critical value,
falls within the critical values,
does not fall within the critical values,
do not reject
reject
the null hypothesis.b. The p-value is
nothing.
(Round to three decimal places as needed.)
Explanation / Answer
here std error =std deviation/(n)1/2 =1.8084
hence test stat z=(X-mean)/std error =(56-54)/1.8084 =1.1060
critical z score for 0.01 level =2.3263
Because the test statistic is less than the critical value do not reject the null hypothesis
p value =0.1344
