It would take the kitten 25 days after its birth to triple its weight.
<u><em>Solution:</em></u>
kitten weighed 100 grams at birth
And gained 8 grams per day
kitten needed to triple its weigh
Which means, they have to become 3 x 100 = 300 grams
Let "x" be the number of days needed to be 300 grams
Then we can say,
300 grams = 100 grams at birth + 8 grams( number of days)
Thus it would take the kitten 25 days after its birth to triple its weight.
Answer:
There is enough evidence to reject the manufacturer’s claim and the standardized test statistic z is -3.43
Step-by-step explanation:
A manufacturer of sprinkler systems designed for fire protection claims that the average activating temperature is at least 135°F.
So, Null hypothesis:
Alternate hypothesis :
To test this claim, you randomly select a sample of 32 systems and find the mean activation temperature to be 133°F.
x=133
n = 32
Population Standard deviation =
Formula :
z=-3.43
Refer the z table for p value
p value = 0.0003
p value < α
So, we failed to accept null hypothesis
Hence there is enough evidence to reject the manufacturer’s claim and the standardized test statistic z is -3.43
Answer:
A. True
Step-by-step explanation:
In Europe and across the world, the tensions from the Cold War affected the borders of various countries, but the two opposing sides were not quick to agree and “forgive” each other, like siblings do.
