Answer:

P-value = 0.2177

Conclusion: The P-value 0.2177 is greater than the significance level 0.05, so we fail to reject the null hypothesis (P = 3/5)

Step-by-step explanation:

Null hypothesis (Ha): P = 3/5

Significance level = 0.05

Decision rule: Reject Ha if the P-value and is less than or equal to the significance level. Fail to reject Ha if P-value is greater than the significance level

Using the standard normal distribution table, the critical value of the test statistic z = 0.78 is 0.7823

P-value = 1 - 0.7823 = 0.2177

The P-value is greater than the significance level, so we fail to reject the null hypothesis (P = 3/5)

Parker wants to ride his bicycle 34 miles this week. He has already ridden 10 miles. If he rides for 5 more days, how many miles
vazorg [7]

Answer: He rode 4.8 miles each day.

Variable: x = Constant distance distance traveledd each day.

Equation : 10+5x=34

Step-by-step explanation:

Total distance needs to travel = 34 miles

Distance already traveled = 10 miles

He will ride bicycle for 5  more days.

Let x = Constant distance distance traveledd each day.

Total distance = 10+5x

i.e.

10+5x=34\\\\\Rightarrow\ 5x=24\\\\\Rightarrow\ x=4.8

Hence, he rode 4.8 miles each day.
