The potential of using solar panels constructed above national highways to generate energy was explored in a particular engineering journal. Two-layer solar panels (with 1 meter separating the panels) were constructed above sections of both east-west and north-south highways in a certain country. The amount of energy (kilowatt-hours) supplied to the country's grid by the solar panels above the two types of highways was determined each month. The data for several randomly selected months are provided in the accompanying table. The researchers concluded that the two-layer solar panel energy generation is more viable for the north-south oriented highways as compared to east-west oriented roadways. Compare the mean solar energy amounts generated for the two types of highways using a 97% confidence interval. Does the interval support the researchers' conclusion? Click the icon to view the data table. Find a 97% confidence interval for μd. Let μd =μ₁₂, where μ₁ is the mean solar energy generated for the east-west highways and μ is the mean solar energy generated for the north-south highways. (Round to one decimal place as needed.)

The potential of using solar panels constructed above national highways to generate energy was explored in a particular engineering journal. Two-layer solar panels (with 1 meter separating the panels) were constructed above sections
of both east-west and north-south highways in a certain country. The amount of energy (kilowatt-hours) supplied to the country's grid by the solar panels above the two types of highways was determined each month. The data for
several randomly selected months are provided in the accompanying table. The researchers concluded that the two-layer solar panel energy generation is more viable for the north-south oriented highways as compared to east-west
oriented roadways. Compare the mean solar energy amounts generated for the two types of highways using a 97% confidence interval. Does the interval support the researchers' conclusion?
