The commercial for the new Meat Man Barbecue claims that it takes 10 minutes for assembly. A consumer advocate thinks that the c
Andrews [41]

Answer:

There is enough evidence to make the conclusion that the population mean amount of time to assemble the Meat Man barbecue is not equal to 10 minutes (P-value=0.009).

Step-by-step explanation:

We have to perform an hypothesis test on the mean.

The null and alternative hypothesis are:

H_0: \mu=10\\\\H_1: \mu \neq 10

The significance level is \alpha=0.05.

The test statistic t can be calculated as:

t=\frac{M-\mu}{s/\sqrt{N} } =\frac{11.2-10}{3.1/\sqrt{50} }=2.737

The degrees of freedom are:

df=N-1=50-1=49

The P-value (two-tailed test) for t=2.737 and df=49 is P=0.00862.

This P-value (0.009) is smaller than the significance level, so the effect is significant. The null hypothesis is rejected.

There is enough evidence to make the conclusion that the population mean amount of time to assemble the Meat Man barbecue is not equal to 10 minutes.

Paladinen [302]

Answer:

  1. FALSE
  2. TRUE
  3. TRUE

Step-by-step explanation:

<u>1.</u>

  • Non-standard units can be used to measure volume
  • Examples : m³, in³, cm³, mm³, L

<u>2.</u>

  • The volume of a rectangular prism can be found by multiplying the length, width, and height
  • <u>V = lwh</u>

<u />

<u>3.</u>

  • If there are smaller units, then naturally more of the units will be used
  • If there are larger units, then less of the units will be used
