Basically imma help h figa this out okay my guy all you need to do it’s dot different spots where the line is on the graph and then figure out those Coordinates on The graph

x axis always come first y axis always is second so it’ll look like this. 1,7 or -4,8 stuff like that okay that’s what it means by relations

Answer:

The probability that the random you randomly select species that are greater than 200 kg is = 7/62

Step-by-step explanation:

Step One: Load the data set in to the R work space

data(mammals,package="MASS")

attach(mammals)

Step 2 : Obtain the list of the species that are greater than 200 and store it on y variable.

y <- subset(mammals,body>200)

Step Three : Obtain the total size

nrow(mammals)

Step Four : Obtain the sum of species greater than 200

sum(body > 200)

total size = 62

size with body > 200 = 7

hence

required probability = 7/62

Answer:

95% confidence interval for the difference between the proportions of Californians and Oregonians is (-0.0070, -0.0130).

Step-by-step explanation:

Confidence interval for a proportion is given as p +/- margin of error (E)

Californians

p = 932/11508 = 0.08

n = 11508

C = 95% = 0.95

Significance level = 1-C = 1-0.95 = 0.05 = 5%

critical value corresponding to infinity degrees of freedom and 5% significance level is 1.96

E = critical value × sqrt[p(1-p) ÷ n] = 1.96 × sqrt[0.08(1-0.08) ÷ 11508] = 1.96 × 0.00253 = 0.0050

Lower limit = p - E = 0.08 - 0.0050 = 0.0750

Upper limit = p + E = 0.08 + 0.0050 = 0.0850

Oregonians

p = 452/4860 = 0.09

n = 4860

critical value = 1.96

E = 1.96 × sqrt[0.09(1-0.09) ÷ 4860] = 1.96 × 0.0041 = 0.0080

Lower limit = p - E = 0.09 - 0.0080 = 0.0820

Upper limit = p + E = 0.09 + 0.0080 = 0.0980

Difference in lower limit of proportion = 0.0750 - 0.0820 = -0.0070

Difference in upper limit of proportion = 0.0850 - 0.0980 = -0.0130

95% confidence interval for the difference in proportion is between a lower limit of -0.0070 and an upper limit of -0.0130.
