Answer:
Therefore we fail to reject the Null hypothesis
Because the is no sufficient evidence to support the claim of the alternative hypothesis
Step-by-step explanation:
From the question we are told that
Sample size 
Mean time 1 
Mean time 2 
Standard deviation 
Standard deviation 
Level of significance 0.05
The null hypothesis is 
Alternative hypothesis 
Generally the test statistics is mathematically represented as




From Table the Z-critical value at 
Therefore
Zcal> Zcritical
(-0.43)=(-1.645)
Generally we fail to reject the null hypothesis
at 
Therefore we fail to reject the
Because the is no sufficient evidence to support the claim of 
Answer:
Cricket match toss and playing cards
Step-by-step explanation:
Example 1: Cricket match toss
<em>There are two teams in a cricket match. Each team's captain comes forward for the toss. There are 2 sides of the coin; head an tail. Each captain has an equal chance of either getting a head or a tail.</em>
Total number = 2
Chances of head/tail = 1
Therefore the probability for each captain of either getting a head or a tail is 1/2.
Example 2: Playing cards
<em>A deck of cards has 52 cards. There are total 26 black cards and 26 red cards out of which there are 13 clubs, 13 spades, 13 hearts and 13 diamonds. Each category has a King, Queen, Jack, Ace, 2, 3, 4, 5, 6, 7, 8, 9 and 10 card.</em>
Total number of cards: 52
Total number of 10 of spades: 1
The probability of getting a 10 of spades will be 1/52.
