Answer:
The dietitian should conclude that there is no significant evidence to support the claim that the number of hours teenagers exercise per week has increased.
Step-by-step explanation:
H0 : μ = 6.5
H1 : μ > 6.5
The test statistic value = 3.30
The critical value > test statistic
The Decison region :
If; test statistic > critical value (Fail to reject H0)
If; test statistic < Critical value (Reject H0)
Given that the test statistic is > critical value ; then we fail to reject the null
Hence, the dietitian should conclude that there is no significant evidence to support the claim that the number of hours teenagers exercise per week has increased.
B. 75.
Explanation: You're more likely to get 75 as the answer because it's in the middle of the symmetric distribution. The equation for the mean average is
sum of all numbers / how many number there are. And at the middle is where all the averages are.
Answer:
100.
Step-by-step explanation:
320,000×100=32,000,000
Answer:
Not true.
Step-by-step explanation:
Whole numbers are integers that are 0 or greater than 0. Since 0 is a whole number and x > 0 does not include 0, the statement is not true. Only the sign ≥ includes 0.
Y=5x-3
the slope is plus 5
so if 1 = 2
simply subtract 5 from two and you get -3
