A specific lake is known to be perhaps the best spot to get a particular sort of fish. In this table, x = number of fish trapped in a 6-hour time frame. The rate information are the rates of anglers who got x fish in a 6-hour time frame while fishing from shore.

x 0 1 2 3 4 or more

% 43% 35% 15% 6% 1%

b)

Discover the likelihood that an angler chose aimlessly fishing from shore gets at least one fish in a 6-hour time frame. (Enter a number. Round your response to two decimal spots.)

(c)

Discover the likelihood that an angler chose aimlessly fishing from shore gets at least two fish in a 6-hour time frame. (Enter a number. Round your response to two decimal spots.)

(d)

Register , the normal estimation of the quantity of fish got per angler in a 6-hour time frame (cycle at least 4 to 4). (Enter a number. Round your response to two decimal spots.)

= fish

(e)

Register , the standard deviation of the quantity of fish got per angler in a 6-hour time span (cycle at least 4 to 4). (Enter a number. Round your response to three decimal spots.)

Utilizing customary techniques, it requires 101 hours to get a high level driving permit. Another preparation procedure utilizing Computer Aided Instruction (CAI) has been proposed. A scientist utilized the method on 90 understudies and saw that they had a mean of 102 hours. Expect the populace fluctuation is known to be 16. Is there proof at the 0.05 level that the strategy performs uniquely in contrast to the customary technique?

Stage 1. Express the invalid and elective speculations.

Stage 2. Discover the estimation of the test measurement. Round your response to two decimal spots.

Stage 3. Determine if the test is one-followed or two-followed.

Stage 4. Discover the - estimation of the test measurement. Round your response to four decimal spots.

Stage 5. Recognize the degree of importance for the theory test.

Stage 6. Settle on the choice to reject or neglect to dismiss the invalid theory
