Answer: 8.3 minutes
Step-by-step explanation:
1 mile is to 1.60934km so 93 million miles is:
= 93 * 1.609
= 149,637,000 km
Travelling at 300,000 km per second, the number of seconds it takes is:
= 149,637,000/300,000
= 498.79 secs
In minutes this is:
= 498.79/60
= 8.3 minutes
Answer:
Step-by-step explanation:
Type I error occurs when the null hypothesis is rejected even when it is true.
Type II error occurs when the null hypothesis is not rejected even when it is false.
The null hypothesis is
The mean annual consumption = the national mean
The alternative hypothesis is
The mean annual consumption < the national mean
1) it is a type II error because the null hypothesis was not rejected even when it is false
2) it is a correct decision because the decision corresponds to the outcome
3) it is also a type II error
d) it is a correct decision because the null hypothesis is accepted when it is true
