Internet prices for glasses are often considerably lower than those at the brick and mortar stores but quality is another questi
on. To address that issue, some optometrists ordered 154 adult pairs of spectacles from various online stores. Of the 154 pairs of spectacles, 44 pairs of eye wear contained at least one lens that did not pass optical analysis testing. Required:
a. Conduct a test of hypotheses with the intent of establishing that the probability of not passing the optical analysis testing is greater than 0.20. Use level of significance 0.05.
b. Calculate the p-value and comment.
We can set up an equation to find the answer. 21/x=0.35/1 because we're trying to find how many starbursts make up 100% of the package. So then to solve, we take 21x1 and then divide that by 0.35. From this we find that x=60.
