Answer:
x = -2.
Step-by-step explanation:
3x + 7 = 1
3x + 7 - 7 = 1 - 7
3x + 0 = -6
x = -6/3
x = -2.
Let P be the population proportion, p be the sample proportion, n be the sample size.
A manufacturer claims that fewer than 6% of its fax machines are defective. It means P=0.06
Sample size n=97 and sample proportion p=0.05
The hypothesis to be tested is
H0: P ≥ 0.06 V/s Ha: P < 0.06
Here the hypothesis for testing population proportion we use z test statistics. Z test statistics is give by
Z = 
Where p =sample proportion = 0.05
p0 = hypothesized proportion value =0.06
Using given values into test statistics we get
Z = 
Z = -0.41
The p-value for left tailed alternative hypothesis is given by
P-value = P(z < z cal)
where zcal = Z test statistics value
Here zcal = -0.41
P-value = P(Z < -0.41)
Using z score table to find probability below z=-0.41
P-value = 0.3409
P-value for testing the given claim is 0.3409
Step-by-step explanation:
Well, 40 - 8 = 32, since she had 8 remaining. Then divide 32 by 2, since she gave 2 to each of her friends. Therefore, she has 16 friends.
-10x + 20 should be the right answer.
