Answer:
There is enough evidence to support the claim the mean nicotine content is actually higher than advertised.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 1.5
Sample mean, = 1.53
Sample size, n = 100
Alpha, α = 0.05
Population standard deviation, σ = 0.17
First, we design the null and the alternate hypothesis
We use one-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now, we calculate the p-value from the standard normal table.
P-value = 0.038807
Since the p-value is less than the significance level we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.
Conclusion:
Thus, there is enough evidence to support the claim the mean nicotine content is actually higher than advertised.

Using proportions, it is found that:
1. 1.4 groups of 5/7 are in 1.
2. The result of 8 divided by 5/7 is of 11.2.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Applying a rule of three, to find how many groups of 5/7 are in 1, we divide 1 by 5/7, hence:
1/(5/7) = 7/5 = 1.4.
Hence 1.4 groups of 5/7 are in 1.
Following the same pattern, for item 2, we have that:
8/(5/7) = 8 x 7/5 = 56/5 = 11.2.
The result of 8 divided by 5/7 is of 11.2.

Answer: E
Step-by-step explanation:
In Parallelogram ABCD and EFGH ,
∠A, ∠B, ∠C and ∠D are corresponding to ∠E, ∠F, ∠G and ∠H respectively.
Since, According to the given question,
parallelogram ABCD is dilated to form parallelogram EFGH,
Therefore, By the property of dilation,
Parallelogram ABCD is similar to parallelogram EFGH,
⇒ ∠A, ∠B, ∠C and ∠D are congruent to ∠E, ∠F, ∠G and ∠H respectively.
Thus Angle A is congruent To angle E.
