Jet Airways CEO Sanjiv Kapoor said Twitter CEO Elon Musk's poll on the reinstatement of Donald Trump's Twitter account was unscientific and not based on a "statistically sound sample set". "Stats was one of my favourite courses at Wharton. Wharton statistics professors must be aghast if this is taken to be scientific...Elon went to Wharton too," Kapoor tweeted.
