10. Laboratory technicians are testing ears of sweet com to see if the hybrid com they're evaluating has more kernels than normal corn. Each car of corn has 16 rows of kernels. The number of kernels per row on the 20 ears they sampled are listed here: 49, 52, 48, 52, 54, 51, 53, 53, 53, 51, 52, 52, 52, 50, 51, 53, 53, 46, 48, 52 What's the average number of kernels per row in the sample of ears? A. 51.25 B. 50 45 C.50.85 D. 51.15

Answer:A. 51.25Step-by-step explanation:Given:Number of samples, [tex]n=20[/tex]The samples are 49, 52, 48, 52, 54, 51, 53, 53, 53, 51, 52, 52, 52, 50, 51, 53, 53, 46, 48, 52.The average number of kernels per row is given as the total sum of all the samples divided by the total number of samples.Therefore, average number of kernels per row is given as:[tex]=\frac{49+ 52+ 48+52+54+ 51+ 53+ 53+ 53+ 51+ 52+ 52+ 52+ 50+ 51+ 53+ 53+ 46+ 48+ 52}{20}\\=\frac{1025}{20}\\=51.25[/tex]
