Meth Barie's ice cream shop wants to decide whether to introduce a new ice cream flavor. They randomly selected 15 customers at

Marianna [84]

Answer:

Meth Barie's ice cream shop should not introduce the new ice cream flavor.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 4.01

Sample mean, $\bar{x}$ = 4.4

Sample size, n = 15

Alpha, α = 0.1

Sample standard deviation, s = 1.6 minutes

First, we design the null and the alternate hypothesis

$H_{0}: \mu \leq 4.01\\H_A: \mu > 4.01$

We use one-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{4.4 - 4.0}{\frac{1.6}{\sqrt{15}} } = 0.968$

Option B) 0.968

Rejection region:

Now, $t_{critical} \text{ at 0.10 level of significance, 9 degree of freedom } = 1.345$

So the rejection region would be a value of t-statistic greater than 1.345.

Option B) t > 1.345

Conclusion:

Since,

$t_{stat} < t_{critical}$

We fail to reject the null hypothesis and accept the null hypothesis. Meth Barie's ice cream shop should not introduce the new ice cream flavor.

Find other values of a, b, and c so that log(a) + log(b) + log(c) = log(a + b + c).

yanalaym [24]

Step-by-step explanation:

Given :

log(a) + log(b) + log(c) = log(a + b + c)

We know that by property

log(a) + log(b) + log(c) = log(abc)

Therefore,

log(abc) = log(a + b + c)

Thus,

(abc) = (a + b + c)

Thus when a = b = c = 0,

then (abc) = (a + b + c)

0 = 0

and when a = 1, b = 2, c = 3,

then (abc) = (a + b + c)

(1 x 2 x 3 ) = (1 + 2 + 3)

6 = 6
