Answer:

V  = 10(n^2 + 7n + 10) inches^3

Step-by-step explanation:

The volume of a rectangular aquarium is V = L*W*H.

Here, V = (n + 2)(10)(n + 5), or

          V  = 10(n^2 + 7n + 10) inches^3.

a researcher found that a cigarette smoker smokes on average 31 cigarettes a day. she feels that this average is too high. she s
Ivenika [448]

At 0.01 significance level the hypothesis is rejected.

Null Hypothesis (H₀): The sample data occurs purely from chance.

Alternative Hypothesis (H₁): The sample data is influenced by some non-random cause.

If the p-value of the hypothesis test is less than some significance level (e.g. α = .01), then we can reject the null hypothesis and conclude that we have sufficient evidence to say that the alternative hypothesis is true.

Given that,

x = 28

s = 2.9

μ = 31

n = 8

α = 0.01

Then, the Null Hypothesis : H₀ = 31

          The Alternate Hypothesis : H₁ < 31

The average number of cigeratte smoker  per day is less than 31.

Test Statistics:

t = x -μ / s√n

   = 28 - 31/ 2.9√8

   = -3/ 8.41

   = -0.356

Since the p-value of 0.0046 is less than the significance level of 0.01, the auditor rejects the null hypothesis.
