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:

The significance level is
.
The test statistic t can be calculated as:

The degrees of freedom are:

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.

Answer:
(5,2)
Step-by-step explanation:
You have to look to the X axis and you'll see the smiley face 5 bars/lines across from the vertex or 0.
Next, you'll need to look at the Y axis and see that the smiley face is 2 bars/lines vertically from 0.
So all you need to do is put the numbers into (x,y) and you'll get (5,2)
Hope this helps!
Answer:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 1010. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
