What is the degree of f?

If the null hypothesis of an experiment is “The true mean weight of the geese is greater than 40 pounds” what is the alternate h

Answer:

The true average weight of geese is less than or equal to 40 pounds

Step-by-step explanation:

The null hypothesis and the alternative hypothesis are two mutually exclusive statements or hypotheses that are made about a population. The purpose is to find out if, through a study of the data, sufficient evidence is obtained to reject one and accept another

The null hypothesis is denoted as $H_0$ and the alternative hypothesis as $H_1$

As they are two mutually exclusive statements then if

$H_0$ : "The true average weight of the geese is greater than 40 pounds"

the alternative hypothesis must be the opposite of the null hypothesis

$H_1$ : "The true average weight of geese is less than or equal to 40 pounds"

A survey of statistics students who had completed BUS 203 revealed that 70% sought additional help at the ICC Learning Lab, whil

Musya8 [376]

Answer:

a) P(NP/L) = 0.1

b) P(P/L) = 0.9

c) P(P) = 0.666

d) P(L/P) = 0.945

e) P(NL U NP) = 0.37

Step-by-step explanation:

given that;

P = passing the course, NP = Not passing the course, L = Using lab, NL = not using Lab

P(L) = 70% = 0.7, P(NL) = 30% = 0.3

P(P/L) = 90% = 0.9

P(P/NL) = 12% = 0.12

a)

the probability of not passing the course given that the student went to the Learning Lab

P(NP/L) = 1 - P(P/L)

P(NP/L) = 1 - 0.9

P(NP/L) = 0.1

b)

the probability of using the Learning Lab and passing the course

P(P/L) = 0.9

c)

the probability of passing the class

P(P) = P(P/L) * P(L) + P(P/NL) * P(NL)

= (0.9 * 0.7) + (0.12 * 0.3)

P(P) = 0.666

d)

the probability that a student utilized the Learning Lab given the condition that the student passed the class

P(L/P) = [P(P/L) * P(L)] / P(P)

P(L/P) = (0.9 * 0.7) / 0.666 = 0.63/0.666

P(L/P) = 0.945

e)

the probability of not using the Learning Lab or not passing the class

P(NL U NP) = P(NL) + P(NP) - P(NP n NL)

= 0.3 + 0.334 - (0.88 * 0.3 )

= 0.634 - 0.264

P(NL U NP) = 0.37

Please anyone its done today 2m2+ 2m − 12 = 0

MrMuchimi

is it factorisatiom or solving equation?

Step-by-step explanation:

2m² + 2m - 12 divide the equation by 2

then: m² + m - 6

factorise: (m + 3)(m - 2)

solve m + 3 =0 or m - 2 =0

m= -3 or m = 2

Someone help me with and tell me how to do it!

MAXImum [283]

Answer:

so what you want to do is change that frac tion to a decimal which would be -.375 then compare that to .27, -3, and 4/6 or .6 repeating now which one is farther from 0? that would be .6 repeating so the answer is d 2/3 because it is equivilant to 4/6
