guajiro [1.7K]

Answer:

The value of the test statistic is <em>z</em> = 3.34.

Step-by-step explanation:

The information provided is:

\bar x=13.4\\\sigma = 4.47\\n=46

The test statistic is:

Z=\frac{\mu-\bar x}{\sigma/\sqrt{n}}

  =\frac{15.6-13.4}{4.47/\sqrt{46}}\\\\=3.33806\\\\\approx 3.34

Thus, the value of the test statistic is <em>z</em> = 3.34.

Complete the equation 0.037 x ? = 37 pls hurry
OleMash [197]

Answer:

The missing number is 1000

Step-by-step explanation:

0.037 × ? = 37

Divide both sides by 0.037.

a = \frac{37}{0.037}

Expand \frac{37}{0.037} by multiplying both the numerator and the denominator by 1000.

a = \frac{37000}{37}

Divide 37000 by 37 to get 1000.

a = 1000

Hope it helps and have a great day! =D
