from this determine the width of each confidence intervals accurate to 3 decimal places.( 90%, 95%, 98%, 99%)when the width interval goes up what would the confidence interval be?

Test your skills about confidence intervals! As one of the world's fastest aging nations and one with high awareness of health, wellness and beauty, Japan has established a lucrative skin care industry in the billions of dollars. Products with anti-aging benefits and corrective properties are in high demand. narDo In this exercise we look at a random sample of Japanese skin care products and their benefits: Anti-Aging Brightening Corrective Softening Frequency 26 13 32 4 75 For the variables "Anti-Aging" and "Softening" check all conditions/assumptions to clarify if the normal model can be used. Explain why or why not for each case. PART I: Construct four confidence intervals with different confidence levels to estimate the percentage of all Japanese skin care products with anti-aging properties. You may use STATCRUNCH to do this work: 1. a 90% CI 1. 645 2. a 95% CI 1:96 3. a 98% CI 2.05 4. a 99% CI 2, 575 Record all confidence interval endpoints in the format (LCL, UCL) accurate to three decimal places: 90%: 6. 256 , 0.437 P = 347 9 = . 653 95%: 0. 239 0.454 n = 75 98%: 0 . 219 0 . 475 P
