Answer:
LCM of 9 and 15 is 45.
Step-by-step explanation:
What is the LCM of 9 and 15?
Find the prime factorization of 9.
Find the prime factorization of 15. 15 = 3 × 5.
Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM: LCM = 3 × 3 × 5.
LCM = 45.
(hope this helps can i plz have brainlist :D hehe)
The 15% tip would be 50*0.15=$7.5
When we reject the null and the null is true, we have a made a type I error
The null hypothesis in statistics states that there is no difference between groups or no relationship between variables. It is one of two mutually exclusive hypotheses about a population in a hypothesis test.
null hypothesis is denoted as H₀
Reject the null hypothesis when the p-value is less than or equal to your significance level. Your sample data favor the alternative hypothesis, which suggests that the effect exists in the population. When you can reject the null hypothesis, your results are statistically significant.
when the p-value is greater than your significance level, you fail to reject the null hypothesis.
Sometimes , we reject our null hypothesis even when its true
there we made a type I error in hypothesis
