As a follow-up to a report on gas consumption, a consumer group conducted a study of SUV owners to estimate the mean mileage for their vehicles. A simple random sample of 84 SUV owners was selected, and the owners were asked to report their highway mileage. The results that were summarized from the sample data were x overbarequals17.4 mpg and sequals5.7 mpg. Based on these sample data, compute and interpret a 99% confidence interval estimate for the mean highway mileage for SUVs

77

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it
