1)Yes,P/E ratio for alternative energy sources=
11.31,16.12,16.7,34.76,36.68
So median is 16.7
While P/E ratio for conventional sources=5.44,9.77,22.13,so median is 9.77 now 150% of median of Conventional = 14.655 ,so it is higher

2)Yes, According to market cap the median is = (61.55+64.38)/2=62.965
So % change for lowest rank=(62.965-21.22)/21.22 =196%
While % change for highest rank = 25.62% decrement,so yes statement is true


3)No,Let the Sum of all yields = S

Now increasing the lowest by 10%= 0.65+0.065=.715
Decreasing the highest by 10% =2.93-.293=2.637

So previous sum of highest and lowest = 3.58
And new sum= 3.352,so the overall avg will decrease

­150 percent higher is wrong calculation if its 9.77 and If P/E for alternative has to be minimum 100 percent higher than it should be min 19.54 so your calculations is not correct for first question

The table shows one quarter's stock market data for eight energy companies, five that specialize in alternative energy sources and three that utilize conventional energy sources. The columns represent, respectively: the name of the company, the company's market capitalization (Market Cap), the Price/Earnings ratio (P/E), the quarterly dividend yield (Div. Yield) and the quarterly price change as represented by a percentage (Price Change).

­Q1. The median P/E ratio for the alternative companies is 16.70, and that for the Conventional companies is 9.77. (16.70-9.77)/9.77~70% higher. False. If it were 150% higher then the median P/E ratio for the Conventional companies should be 9.77*250/100~24. False.

Q2. The median value of the market capitalization is ~63. If we sort the column Market Cap (Millions), we can see the differences from the median for the first four values are much higher(approx 197%, 41%, 15% and 2%) than the differences for the last four (2%, 7%, 17%, 26%). True.

Q3. The average dividend yield at first is ~1.72. If we increase the lowest dividend yield i.e. 0.65 by 10% then it becomes 0.715 and if we decrease the highest dividend yield i.e. 2.93 by 10% then it becomes 2.637. The new average is ~1.69 so not the same. False.
