In a certain city, the population mean commute time to work was reported as 30 minutes. The director of human resources for a certain company in the city claimed the mean commute time for the
company's employees was greater than 30 minutes. The director surveyed 35 randomly selected employees and found that their mean commute time was 31.4 minutes. With all conditions for
inference met, a hypothesis test conducted at the significance level a = 0.05 resulted in a p-value of 0.381
Which of the following is an appropriate conclusion?
Answer:
Answer.The director does not have convincing statistical evidence to conclude that the population mean commute time is greater than 30 minutes.
Because the p value is very high and higher than level of significance ,so we fail to reject null hypothesis.

Use the drawing tools from the correct answer on the graph.
Plot function g on the graph.
g(x) = 6, -7 < x < -2
2, -2 < x < 3
-2, 3 < x < 8
The function g(x) is a discrete function. It is continuous between -7 to -2, -2 to 3, and 3 to 8. And the open circle at -7, -2, 3, and 8. And the jump of the g(x) is 4 units after every interval.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

A sum amounted naira 2,590
at 10% Per annum for the
Period of 4 Years. Find the sum
Answer:
1,769
Step-by-step explanation:
The computation of the sum is shown below:
Future value = Present value × (1 + rate of interest)^number of years
2,590 = Present value × (1 + 0.10)^4
2,590 = Present value × 1.10^4
So, the present value is
= 2,590 ÷ 1.10^4
= 2,590 ÷ 1.4641
= 1,769

a baker bought 12 pounds of flour.He used 5/6 of the flour how many pounds are left
Answer:
2 pounds are left.
Step-by-step explanation:
12 pounds divided into 6 parts (or sixths) = 2 pounds each. 5 of those 6ths were used, so 10 pounds used. 2 pounds are left.
Alternately, multiply 12 x 5 for your numerator = 60, divide by 5, your denominator, and get 10 pounds used.
Simplify each expression by combining like terms:

Answer:
yes
Step-by-step explanation:
The mode is the measure of the central tendency for the given data set. The mode represents the highest frequency of the number
Since in the given data set as we can see that the 100 would be appeared 6 times
So this represent that the mode is 100
So here the mode would be the good measure
