Many things affect coral such as, temperature not hot, or not to cold but warm, but between 70-85 degrees F and 21-29 degrees C. They need a plethora.

Presentation transcript:

Many things affect coral such as, temperature not hot, or not to cold but warm, but between degrees F and degrees C. They need a plethora of wave action, so the corals have enough oxygen to survive. Corals need shallow water to survive, because then the sun can give off sunlight to them. Corals need clear water, so the sunlight can go through the water and to the coral. They also need clean water, because the coral is sensitive to pollution and sediments. Probability is a way to measure the chances that something will occur in relation to the possible alternatives.

Variance- Two values that are used in statistics to describe how far away your data are from the mean

Ideal picture of a distribution based upon random sampling

A t-test equation you will use to calculate the t-statistic is one designed to test whether there is a significant difference between the means of two independent samples, those of your treatment and control groups. This equation includes the mean, the number, the variance, and the probability. The probability must be less than 0.05.

p= Since p <.05, we reject the null hypothesis, and accept the alternative hypothesis. Therefore, there is a significant difference in Survival rates between Beach Sites. A Chi-square Test can be used to see if there are any significant differences between data sites or sources. We found these results by playing a sea turtle game. Everybody started out with 25 sea turtles and would have to get to the end with at least 1 turtle alive. Beach Sites ABCDE Actual Expect46
