Explain why the​ t-distribution has less spread as the number of degrees of freedom increases. Choose the correct answer below.
Tems11 [23]

Answer:

B. The​ t-distribution has less spread as the degrees of freedom increase​ because, as n​ increases, s becomes closer to sigma by the law of large numbers.

Step-by-step explanation:

The sample standard deviation, s gets considerably closer to the population standard deviation, σ, this trend follows the proposition of the law of large numbers whereby the mean or average value changes as the sample size, n increases. According to the law of large numbers, as the sample size increases, the sample mean gets continously closer to the population mean, sample standard deviation follows this same trend and thus variability or spread decreases as sample size increases.

A family has two cars. During one particular week, the first car consumed 20 gallons of gas and the second consumed 30 gallons o
Alex Ar [27]
<span>Fuel consumed by Car A = 20 gallons Fuel consumed by Car B = 30 gallons Total distance = 950 miles Let, distance covered by Car A = X miles As the total distance covered is 950 miles, Distance covered by Car B = 950 - X miles Efficiency is calculated as total distance travelled divided by total fuel consumed. Efficiency of Car A = X/20 miles/gallon Efficiency of Car B = (950 - X)/30 miles/gallon It is given that sum of efficiencies is 40. So, (X/20) + (950 - X)/30 = 40 X/20 can be represented as 3X/60 and (950 - X)/30 can be represented as (2*(950-X)/60) to make the denominator same. (3X/60) + (2*(950-X)/60) = 40 Simplifying, we get (3X + 1900 - 2X)/60 = 40 Simpifying further, we get X + 1900 = 2400 X = 2400 - 1900 X = 500 So, distance covered by Car A = 500 miles Distance covered by Car B = 950 - 500 = 450 miles To calculate fuel efficiencies, Efficiency of Car A = 500/20 = 25 miles/gallon Efficiency of Car B = 450/30 = 15 miles/gallon</span>
