Answer:
There is no enough evidence to reject the claim using a level of significance of 5%
Step-by-step explanation:
Let p be the true proportion of homeowners in Omaha who own a lawnmower. We want to test
vs (two-tailed alternative).
We have a large sample of size n = 500 and a point estimate for p is . The test statistic is given by
where is the standard error of when is true. The observed value is = 1.4064 which comes from a standard normal distribution. Because we want to use a level of significance of 5%, our rejection region is RR={z | z < -1.96 or z > 1.96} where -1.96 and 1.96 are the 2.5th and 97.5th quantiles respectively. Because 1.4064 does not belong to RR, we fail to reject the null hypothesis.
Well
solve the expressions first
a) 4-6=-2 b) -4+6=2 c) -4-6=-10
so least to greatest would be c, a and then b
Answer:
1/2 = m
Step-by-step explanation:
3/4=m+1/4
Subtract 1/4 from each side
3/4 - 1/4=m+1/4-1/4
2/4 = m
Simplify
1/2 = m
Answer:
It is.
Step-by-step explanation:
1.5cm is in the plan.
1.92m is in real life.
We need to convert m to cm so 1.92m=192cm
The ratio is 1:128.
1.5cm in plan as is 192 cm in real life.We write that as the ratio of: 1.5 : 192.
We need to prove that it is the actual scale so we equal this ratio(1.5:192) and the other ratio(1:128):
1.5 : 192 = 1 : 128
Then we multiply the numbers that are in and out of the equation like this:
1.5 * 128 = 192 * 1
192 = 192 It is proven beacuse the numbers are equal. The scale of the house is 1:128
