Emma wants to check the p-value of an experiment of filling 250 boxes of mango juice according to the status 100ml. Calculate the p-value of the experiment if the z-value for one-tailed is 0.35
Solution
Step 1: First of all, make the null and alternative hypotheses of the given experiment.
Null hypothesis = h0 = quantity of mango juice in the boxes is 100ml
Alternative hypothesis = ha = quantity of mango juice in the boxes is different from 100ml
Step 2: Now find the test statistics of the given experiment according to the given values.
The test statistics of the given experiment are already given.
Z value = 0.35
Step 3: Now take a standard distribution table and indicate the corresponding value on that table.
The value on the standard distribution table is 0.36317
Note: If the test or z value is two-tailed then you have to multiply the corresponding value on standard distribution table by 2.
