A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 449 gram setting. It is

stealth61 [152]

Answer:

We accetp H₀

Step-by-step explanation:

Information:

Normal distribution

Population mean = μ₀ = 449

Population standard deviation σ unknown

Sample size n = 23 n < 30 we use t-student test

so n = 23 degree of fredom df = n - 1 df = 23- 1 df = 22

Sample mean μ = 448

Sample standard deviation s = 20

Significance level α = 0,05

1.-Hypothesis Test

Null hypothesis H₀ μ₀ = 449

Alternative hypothesis Hₐ μ₀ ≠ 449

Problem statement ask for determine decision rule for rejecting the null hypothesis. For rejecting the null hypothesis we have to get an statistic parameter wich implies that μ is bigger or smaller than μ₀

2.-Significance level α = 0,05 ; as we have a two tail test

α/2 = 0,025

Then from t - student table for df = 22 and 0,025 (two tail-test)

t(c) = ± 2.074

3.- Compute t(s)

t(s) = ( μ - μ₀ ) / s /√n

plugging in values

t(s) = (448 - 449) / 20 /√23 ⇒ t(s) = - 1*√23 /20

t(s) = - 0.2398

4.-Compare t(c) and t(s)

t(s) < t(c) - 0.2398 < - 2.074

Therefore t(s) in inside acceptance region. We accept H₀

The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate

amid [387]

Answer:

It takes 7.37 hours for the size of the sample to double.

Step-by-step explanation:

Continuous exponential growth model:

The continuous exponential growth model for populations is given by:

$P(t) = P(0)e^{rt}$

In which P(0) is the initial population and r is the growth rate parameter, as a decimal.

Growth rate parameter of 9.4% per hour.

This means that $r = 0.094$

So

$P(t) = P(0)e^{rt}$

$P(t) = P(0)e^{0.094t}$

How many hours does it take for the size of the sample to double?

This is t for which P(t) = 2P(0). So

$P(t) = P(0)e^{0.094t}$

$2P(0) = P(0)e^{0.094t}$

$e^{0.094t} = 2$

$\ln{e^{0.094t}} = \ln{2}$

$0.094t = \ln{2}$

$t = \frac{\ln{2}}{0.094}$

$t = 7.37$

It takes 7.37 hours for the size of the sample to double.

Students collected money for a trip. Each of the 21 student contributed the same amount. How much did each student contribute, i

MakcuM [25]

Answer:

$12.40

Step-by-step explanation:

Because each of the students paid the same amounts, you just divide the total amount of money by the number of students there are, which is 21 and you get your answer of $12.40. hope this helps :)
