Please give an explanation on how you got the answer.
The normal distribution has the following probability distribution: 4.19 34.1 2.1% 2.3% 0.1% 0.1% 13.6% 13.6% -30-20-10 0 1 20 30 Q1 Why did Literary Digest fail to predict the outcome of the 1936 presidential election? 1. Because they did not have sufficient money for the survey. 2. Because they collected data from unreliable sources 3. 4. 5. Because they used an internet survey. Because they used a telephone survey. Because they collected very small data. 02 Supply-demand mismatch could occur in an electric power system. In the summer time, the demand of electricity is high during the daytime, while the demand is low at night. The supply (capacity) of electricity is set to the peak time (daytime). To reduce the supply-demand mismatch in an electric power system, which strategy does NOT contribute to the reduction of the mismatch? 1. Increase the price of electricity during the daytime. 2. Decrease the price of electricity at night 3. Encourage people to install solar panels on their roofs to generate extra electricity during the daytime. Build more power stations to supply more electricity to all companies/houses. 4. Ask companies to refrain from using air-conditioners during the daytime.Explanation / Answer
Q1) Literary Digest failed to predict the outcome of the 1936 presidential election -
5. Because they collected very small data
Small sample data doesn't provide an accurate representation of the population, hence based on small data, the results will not be accurate leading to the failure of the prediction.
Q2) The strategy that does not continute to the reduction of the supply-demand mismatch is -
4. Build more power stations to supply more electricity to all companies/houses
Building more power stations will increase the supply but doesn't balance the supply and demand during the day and night times whereas rest of the options will either try to reduce the demand during day time or increase the demand during night time.
