The latest 4K TVs are very sophisticated pieces of technology. They have to be built to a very high standard. All companies employ a quality control person to make random tests regularly to make sure 95% of the 4K TVs they build meet their standards. The null hypothesis of the test is that the proportion of all 4K TVs produced meet a specified standards is equal to 95 percent. The alternative hypothesis is that the proportion of all 4K TVs produced that meet their standards is greater than 95%.

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

by the low of sine,

which is the required equation for finding the value of x,

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .
