Create the following indices, giving them an appropriate name in your spreadsheet (make sure to use the reverse-coded variable where relevant): Belief that climate change is a real phenomenon: Take the mean of scepticism_2, scepticism_6, and scepticism_7. Preferences for government intervention to solve problems in society: Take the mean of cog_1, cog_2, cog_3, cog_4, cog_5, and cog_6. Feeling of personal responsibility to act pro-environmentally: Take the mean of PN_1, PN_2, PN_3, PN_4, PN_6, and PN_7. When creating indices, we may be interested to see if each item used in the index measures the same underlying variable of interest (known as reliability or consistency). There are two common ways to assess reliability: either look at the correlation between items in the index, or use a summary measure called Cronbach’s alphaCronbach’s alpha A measure used to assess the extent to which a set of items is a reliable or consistent measure of a concept. This measure ranges from 0–1,…

I need help with this python code 1. The starter code has been created for you. 2. Using the Yahoo Finance module, download the stock data for the stocks AMC and GME between December 1, 2021 and around the day you started this exercise (June or July 2021) in intervals of one day. You will focus only on the Close price and Volume traded. 3. Using the data downloaded from yfinance, create a new DataFrame that contains these five columns: Day, AMC Close, AMC Volume, GME Close, and GME Volume. Note the index for the DataFrame is the YYYY-MM-DD date, but you will need to make it a column. 4. Apply pd.melt() to this new DataFrame created in Step 3, such that the Day column is kept. The variable column will contain either AMC Close, AMC Volume, GME Close, and GME Volume. Rename this column to 'Type'. The values column will contain either the closing price or the volume traded for the respective stock on that day. 5. Create a FacetGrid of four lineplots on the stock data using the DataFrame…
