please help me solve the missed questions based on the last picture

This value is the probability that the correlation between the variables is statistically significan OD. The coefficient of determination is R This value is the probability that the slope of the regression line is statistically significant Interpret the values given in the test of the population slope. Use a 0.05 level of significance. State the null an 0 Ho P. . . + (Type integers or decimals. Do not round.) Identify the test statistic t = 4.88 (Round to two decimal places as needed.) Identify the p-value The p-value is 0.000 (Round to three decimal places as needed.)

State the conclusion Reject Ho There is sufficient evidence of a linear relationship between wedding cost and attend a 3 as Identify the p-value The p-value is 0.000 (Round to three decimal places as needed.) State the conclusion Reject Ho There is sufficient evidence of a linear relationship between wedding cost and attendance Identify and interpret the 95% confidence interval estimate of the population slope.

The confidence interval is 75 200 B.'s 185.791 With 95% confidence it can be said that true expected mean increa confidence interval (Round to three decimal places as needed) c. If a couple is planning a wedding for 225 guests, how much should they budget?
