Calculate the density of benzene if 300ml of it weighs 263g. a. 0.88 g/ml b. 1.14 g/ml c. 78,900 g/ml d. 37 g/ml

A

Step-by-step explanation:

Formula

d = m/V

Givens

Solution

d = 263 / 300

d = 0.8767 grams / mL

The test statistic for this hypothesis test =1.597

Step-by-step explanation:

When population standard deviation is unknown, we use t-test statistic:

= sample mean, = population mean , s= sample standard deviation, n = sample size.

As per given,

Hence, the test statistic for this hypothesis test =1.597
