Solution: The sample mean of sample 1 is:
The sample mean of sample 2 is:
The sample mean of sample 3 is:
The sample mean of sample 4 is:
The minimum sample mean of the four sample means is 3.6 and maximum sample mean of the four sample means is 4.4.
Therefore, using his four samples, between 3.6 and 4.4 will Ardem's actual population mean lie.
Hence the option 3.6 and 4.4 is correct
Answer:
a) θ = b) r = 31.27 inch
Step-by-step explanation:
(a)
area of sector: * r² * θ
384 = * r² * θ
384 = * (24)² * θ
θ = 384/288
θ =
(b)
384 = * r² *
r² = 384 * 2 *
r² = 977.848
r = √977.848
r = 31.27 inch
