nlexa [21]

Answer:

Decison region :

Reject H0 : if χ² > 6.251

12.229

Step-by-step explanation:

Given :

Manufacturer A B C D

Unacceptable 29 17 9 22

Acceptable 171 183 191 178

Total 200 200 200 200

H0: There is no relationship between quality and manufacturer.

H1: There is a relationship.

Testing using the goodness of fit :

Chisquare = (observed - Expected)² / Expected

Expected Values:

19.25 19.25 19.25 19.25

180.75 180.75 180.75 180.75

Chi-Squared Values:

4.93831 0.262987 5.45779 0.392857

0.525934 0.0280083 0.581259 0.0418396

χ² = 4.93831 + 0.262987 + 5.45779 + 0.392857

+ 0.525934 + 0.0280083 + 0.581259 + 0.0418396 = 12.229

Degree of freedom, df = (4-1)(2-1) = 3*1= 3

The critical value,

χ² at 0.10, 3 = 6.251

Decison region :

Reject H0 : if χ² > 6.251

Reject H0 : 12.229 > 6.251

A child requires a 5ml dose of medicine each day. how many days would a gallon of this medicine last.

OLga [1]

in a US gallon, there are approximately 3.79 Liters, in a Liter there are 1000 milliLiters, so 3.79 Liters is then 3.79 * 1000 milliLiters, namely 3790 milliliters.

since a gallon is then approximately 3790 mL, how many times does 5mL go in to 3790? 3790 ÷ 5 = 758.

since the child uses 5mL in 1 day, then 758 times that is 758 days.

Correct answer will get brainliest.

Alecsey [184]

Answer:

B) 1

Step-by-step explanation:

The smallest integer larger than 0.6 is 1.

___

The funny single-ended brackets signify the "ceiling" function. If the bent end is at the bottom, the "floor" function is indicated. The "ceiling" function returns the smallest integer not less than the given value. The "floor" function returns the largest integer not greater than the given value.

These are more commonly used than you might think. For example, the charge in a parking lot may be for a number of hours or fraction thereof. That is an expression of the ceiling function applied to hours. In this problem, that would mean that parking for 0.6 hours would be charged as 1 hour.
