so, test statistic value would be

At 1% level of significance, critical value would be
z= 2.58
Since 2.58>-1.604
So, We will accept the null hypothesis.

Answer:
4+x>13
x>9
Step-by-step explanation:
This statement represents an inequality. To solve for the missing number first write out the inequality algebrically.
"Four more" implies that 4 is being added to the number. Another way to "a number" is to use the variable, x. So, the left side of the inequality is 4+x. Then, it says that this is "more than" 13. Thus, the greater than sign, >, should be used. This means that the final inequality is 4+x>13.
Next, you can solve the inequality by subtracting 4 from both sides. This gives x>9.
3/4x4=3 therefore she needs 3 cups of flour to make four batches of cookies : )
4 of you divide 6 by 1.25 it's 4.8 but for a whole bows it's 4
