Answer:
Reject H0
Step-by-step explanation:
Given :
H0: The frequencies are equal. H1: The frequencies are not equal
Category f0 A 10 B 30 C 30 D 10
Total f0 = (10 + 30 + 30 + 10) = 80
Expected frequency is the same for all categories :
Expected frequency = 1/4 * 80 = 20
χ² = Σ(observed - Expected)² / Expected
χ² = (10-20)^2 / 20 + (30-20)^2 /20 + (30-20)^2 / 20 + (10-20)^2 / 20
χ² = (5 + 5 + 5 + 5) = 20
Pvalue = 0.00017
Pvalue < α
Its A. multiply both sides by 3
the answers are : for m<5 it is 75 degrees, for m<11 i think it is 75 degrees, and m<16 it is 65 degrees
Hello there!
Soo..to convert a number from standard notation to scientific notation you first have to write a decimal point in the number so that there is only one digit to the left of the decimal point. Sooo for example if u had 240,000 you would put the decimal after the 2 (2.40000)
Hope this helped and have a great day!!
Goodluck (:
B) thats the only one i could think of that would even sound right
