1 answer:
Answer:
minutes
Step-by-step explanation:
We can us rule of three to solve this problem.
We have that 3 laps are done in 8 minutes, and we want to know how much time it will take to run 10 laps:
laps minutes
3 ----------->8
10----------->
To find the value of x we do as follows:
minutes
we cross multiply the values, and divide by the remaining value, thus we have the time it takes to run 10 laps is 26.27 minutes

Answer:
There is not enough evidence to support the claim that Alaska had a lower proportion of identity theft than 23%.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 1432
p = 23% = 0.23
Alpha, α = 0.05
Number of theft complaints , x = 321
First, we design the null and the alternate hypothesis
This is a one-tailed test.
Formula:
Putting the values, we get,
Now, we calculate the p-value from the table.
P-value = 0.298
Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.
Conclusion:
Thus, there is not enough evidence to support the claim that Alaska had a lower proportion of identity theft than 23%.
