Answer:
can be either a representation of the entire or a sample of a population. Descriptive statistics are broken down into measures of central tendency and measures of variability (spread).
Step-by-step explanation:
Answer:
Yes,there is a significant association shell weight and the widths of the opercula
Step-by-step explanation:
Using a correlation Coefficient calculator :
Given the data above :
The Coefficient of correlation(r) obtained is :
0.7632
Obtaining the test statistic :
T = r² / √(1 - r²) / (n - 2)
T = 0.7632² / √(1 - 0.7632²) / (10 - 2)
T = 0.58247424 / 0.2284528
Test statistic = 2.550
The Pvalue from r score , N = 10
Pvalue(0.7632, 10) = 0.01022
α = 0.05
If Pvalue < α ; reject H0
Pvalue < α ; We conclude that there is a significant association shell weights and the widths of the opercula
Answer:
52 x 7= 50 x 7 + 2 x 7
Step-by-step explanation:
You will only need 2.83% of the 34 cm cube
Answer:
m(∠R) = 5°
Step-by-step explanation:
By applying sine rule in the given triangle RST.
sin(∠R) = 
= 0.09237
m(∠R) = 
= 5.3°
≈ 5°
