artcher [175]

Hey You!

350 * 10% = 35

350 - 35 = 315

315 / 5 = 63

63 × 3 = 189

315 - 189 = 126

There are 126 red keys in the bin! =)

A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 419 gram setting. It

Pachacha [2.7K]

Answer:

We reject the null hypothesis, and accept the alternative hypothesis.

So, it means that the machine is under filling the bags

Step-by-step explanation:

Given

Null Hypothesis

$H_0:\mu = 419$ --- works correctly at 419g

Alternate Hypothesis

$H_0:\mu < 419$ --- under fills the bag

$n =15$ --- the sample

$\bar x = 409$ --- the mean

$\sigma = 22$ --- the standard deviation

$\alpha = 0.05$ --- the significance level

Required

What is the decision rule

Since n is less than 30, we make use of t test

$t = \frac{\bar x - \mu}{\sigma/\sqrt n}$

$t = \frac{409 - 419}{22/\sqrt{15}}$

$t = \frac{-10}{22/ 3.87}$

$t = \frac{-10}{5.58}$

$t = -1.792$

Calculate df

$df = n-1$

$df = 15-1$

$df = 14$

Calculate the p value from the Student's t-distribution at df = 14 and $t = -1.792$

$p =0.047$

Given that: $\alpha = 0.05$

Since $p < \alpha$

So, it means that the machine is under filling the bags

26-16=10. So I believe it would be 10 girls and 6 boys.

____ [38]

Answer:

The mean is 4.88 hours / day

Step-by-step explanation:

To calculate the mean we just add the values and divide by the number of items (in this case we add the hours and divide by the number of days)

so the equation would be

$\frac{1.7+7.7+8.3+1.6+5.1}{5}=4.88$
