Answer:

Test statistic (t) = 0.625

Step-by-step explanation:

Step(i):-

mean of the Population(μ) = 10.4 hours

Sample mean (x⁻) = 10.7 hours

Standard deviation of the sample( S) = 1.44

The level of significance (α= 0.1

Sample size 'n' = 9

Degrees of freedom = n-1 = 9-1 =8

Step(ii):-

Test statistic

$t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }$

$t = \frac{10.7 -10.4}{\frac{1.44}{\sqrt{9} } } =0.625$

Olegator [25]

Grass can grow up to six inches in a week depending on temperature, humidity, and time of year

We have to calculate how tall will grass grow in 24 days

we know there are seven days in a week

so in one day grass can grow up to 6/7 inches

therefore we could say that grass can grow up to 24*6/7 inches

so the answer is 20.57 inches

so in 24 days grass can grow up to 20.57 inches
