Answer:
The required steps are shown below:
Step-by-step explanation:
Consider the provided information.
The required steps are:
Step 1: First he need to collect the sample which should be randomly selected and sample size should be large.
Step 2: Find [tex]\bar{x}[/tex] of the sample.
Step 3: Find the standard deviation.
Step 4: Use null and alternative hypotheses:
[tex]H_0 : \mu = 0.012 \newline H_a : \mu > 0.012[/tex]
Step 5: Take [tex]\mu = 0.012[/tex] and level of significance α = 0.05
Step 6: Population Variance is unknown so conduct A right tailed t test and obtain the value of test statistic t and p-value .
Step 7: If p-value is < 0.05, Reject null hypothesis, else Do not reject null hypothesis.
Step 8: Give conclusion on the basis of whether null hypothesis is rejected or not.
